What would be the most likely effect of a wildlife that burned a large area of a forest?
What would be the most likely effect of a wildfire that burned a large area of a forest? More sugars and starches would be available for animals in the area. The availability of fossil fuels for use by industries in the area would be reduced.
Which statement provides the best explanation for the difference in biomass of organisms found at each tropic level?
Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level? Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
Why do decomposing pioneer plants give way to larger more complex plants?
During secondary succession, which of the these best describes why decomposing pioneer plants give way to larger, more complex plant species, such as hardwood trees? Increased amounts of soil from decomposing pioneer species allow plants with more extensive root systems to become established.
What effect does continual mowing have on the ecology of the field?
What effect does continual mowing have on the ecology of the field? A Mowing increases the likelihood of nonnative species displacing native species.
What organisms benefit from wildfires?
Some species benefit from wildfire, such as raptors that hunt rodents running from the flames, beetles that move into dead wood and lay eggs, and woodpeckers that feed on them and nest in hollow trees. Fire exposes new grass, shrubs and vegetation in the flowering stage that feed elk and deer.
Can burned forest burn again?
Depending on the severity of the wildfire, a forest may recover quickly. (The low-intensity “prescribed fires” used by forest managers, for example, are intended to add nutrients to the soil and rejuvenate plant life.) For larger, more destructive wildfires, active efforts to assist recovery are often needed.
How does biomass affect trophic levels?
Trophic Levels and Biomass Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level. The decrease in biomass from lower to higher levels is also represented by Figure above.
Why biomass of producers is greater than that of primary consumers?
Why producers are more than consumers? Producers can produce their own food like plants through photosynthesis but consumers cant produce food so they depend on producers for food. if consumer increases the number of producers decrease so to maintain ecological balance the number of producer is more than consumers.
Which statement best explains the importance of the root hairs to the stems and leaves of the plant?
Which statement best explains the importance of the root hairs to the stems and leaves of the plant? Root hairs increase the surface area of the roots for nutrient and water absorption.
Which of the following is most likely to cause an ecosystem to become unstable?
1 Answer. Removal of native species. Introduction of new species. Pollution, toxification of an area.
How does mowing affect biodiversity?
Mowing urban lawns less intensely increases biodiversity, saves money and reduces pests. Summary: Researchers have found that reducing the intensity of lawn mowing in urban spaces leads to increased biodiversity, economic savings and reduced presence of allergy-triggering weeds.
What is the primary role of decomposers in an ecosystem?
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
What are the positive and negative effects of wildfires?
Fire is often associated with negative impacts on the environment. We usually think of the damage and devastation fire causes to wildlife and vegetation, but a fire event can also be beneficial for our plants and animals. For example, fire: heats the soil, cracking seed coats and triggering germination.
What plants benefit from forest fires?
Some plant species depend on fire for survival as well. This is very true for the endangered plant species like the sandplain gerardia and the wood lily; both of these plants depend on the forest fires to multiply and grow. These plants grow in areas where non-native invasive plants take over their habitat.
Are rosemary plants fire resistant?
Examples of highly flammable plants include ornamental juniper, Leyland cypress, Italian cypress, rosemary, arborvitae, eucalyptus, and some ornamental grasses. Care should be taken to not place fire prone plants adjacent to any structures and preferably not within 30 feet of the house.
What is a pioneer tree?
Trees like alders, poplars, birches and willows are dubbed “pioneer species” in forestry. They earn that nickname for often being the first trees to colonize sites disturbed or damaged by landslides, fires, floods or clear cuts. Pioneer species grow rapidly and establish new canopies faster than competing vegetation.
What roles do protists play in the trophic structure of their communities?
Protists function at several levels of the ecological food web: as primary producers, as direct food sources, and as decomposers. In addition, many protists are parasites of plants and animals that can cause deadly human diseases or destroy valuable crops.
Which trophic level has the most energy?
producers Each level or step in a food chain where the transfer of energy takes place is called trophic level. According to the pyramid of energy, the energy content is maximum in autotrophs or producers.
Which organism gets the greatest amount of energy?
autotrophs According to the pyramid of energy, the energy content is maximum in autotrophs or producers. Autotrophs are the plants which prepare their food by photosynthesis.
What organism has the greatest biomass which has the greatest energy?
The most successful animal species, in terms of biomass, may well be Antarctic krill, Euphausia superba, with a fresh biomass approaching 500 million tonnes. However, as a group, the small aquatic crustaceans called copepods may form the largest animal biomass on earth.
What advantages do root hairs give to a plant?
Because they vastly increase the root surface area and effectively increase the root diameter, root hairs are generally thought to aid plants in nutrient acquisition, anchorage, and microbe interactions (Cutter, 1978; Hofer, 1991).
Which statement best explains the importance of the root hairs to the stems and leaves of the plant a root hairs convert minerals into glucose for immediate use by cells?
Which statement best explains the importance of the root hairs to the stems and leaves of the plant? Root hairs increase the surface area of the roots for nutrient and water absorption.
Which can have the most impact on an ecosystem?
Unnatural occurrences can have the most significant impact on an ecosystem. ___________ ecology focuses on how human activities affect an ecosystem and ways to mitigate resulting issues. Select all that apply. What factors can limit growth?
Which ecosystem has the most stable condition?
Oceans are the most stable ecosystems. Other terrestrial ecosystems undergo changes and succession of biotic components. But oceans remain stable for the long duration of time.
Is cutting your grass good for the environment?
But all that competition has a devastating environmental impact. Every year across the country, lawns consume nearly 3 trillion gallons of water a year, 200 million gallons of gas (for all that mowing), and 70 million pounds of pesticides.
Does grass help the environment?
Maintaining a healthy, thick lawn also benefits the environment. Unlike hard surfaces such as concrete, asphalt, and wood, lawn grass helps clean the air, trap carbon dioxide, reduce erosion from stormwater runoff, improve soil, decrease noise pollution, and reduce temperatures.
Why are decomposers beneficial to the soil?
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
What is the role of decomposers in an ecosystem choose more than one answer?
Why are decomposers an important part of ecosystems? They break down dead organisms to return nutrients to the soil. They produce their own food for survival. They play a role in preventing weathering and erosion.
What are positive effects of forest fires?
Fire removes low-growing underbrush, cleans the forest floor of debris, opens it up to sunlight, and nourishes the soil. Reducing this competition for nutrients allows established trees to grow stronger and healthier.
What is the positive and negative effects of fire and how it affects our environment?
It plays a key role in shaping ecosystems by serving as an agent of renewal and change. But fire can be deadly, destroying homes, wildlife habitat and timber, and polluting the air with emissions harmful to human health. Fire also releases carbon dioxide—a key greenhouse gas—into the atmosphere.
