Which biome has fairly dry and warm climate and primarily contains grasses with scattered isolated trees?
The grassland biome is made up of large open areas of grasses. They are maintained by grazing animals and frequent fires. Types of grasslands include savannas and temperate grasslands.
Why are photosynthetic algae limited to surface water?
Why are photosynthetic algae limited to surface water in marine ecosystems? Visible light cannot penetrate deeply into the ocean, even when the water is clear.
What is the primary role of a decomposer in the chemical cycling of elements in the biosphere quizlet?
What is the primary role of a decomposer in the chemical cycling of elements in the biosphere? Decomposers break down large organic molecules into smaller, more accessible nutrients.
What type of survivorship curves do humans typically display?
The survival curve of modern humans is described as a classic “Type-I”, where the probability of survival is high until relative old age, whereby it then declines rapidly, which is typical of many large mammals.
Which biome has a permanently frozen layer of soil called permafrost?
Tundra winters are long, dark, and cold, with mean temperatures below 0°C for six to 10 months of the year. The temperatures are so cold that there is a layer of permanently frozen ground below the surface, called permafrost. This permafrost is a defining characteristic of the tundra biome.
What biome is humid due to its warm temperatures and abundant rainfall?
The tropical rainforest is a hot, moist biome where it rains all year long. It is known for its dense canopies of vegetation that form three different layers.
What is surface water PDF?
Surface water is water on the surface of the planet such as in a river, lake, wetland, or ocean. It can be contrasted with groundwater and. atmospheric water. Non-saline surface water uses is replenished by precipitation and by.
Why are flood plain soils particularly fertile?
Flood plains are naturally very fertile due to the river sediment which is deposited there. This sediment is good for growing plants on the flood plain.
How does decomposition help in the recycling of nutrients among living things and their environment?
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 would happen to an ecosystem if all of its decomposers and detritus feeders were eliminated?
Answer a) If Decomposers and detritus feeders eliminated Then Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem.
How might the removal of a wetland affect a nearby city?
It will seasonally dry up and cease to be a biome. It is the transition zone between freshwater and saltwater biomes. How might the removal of a wetland affect a nearby city? Wetlands cause flooding.
What is an ecological footprint quizlet?
Ecological Footprint. – A measure of the amount of biologically productive land and water area an individual, a population or an activity occupies, given prevailing technology. – This area includes the space to produce the resources consumed and to absorb the waste that has been created.
Which biome is made up of trees that do not lose their leaves in the winter?

| which biome has a rainy season and a dry season? | savanna |
| What is the biome called where fresh and salt water meet? | estuary |
What biome has all 4 seasons?
Temperate deciduous forests Temperate deciduous forests are most notable because they go through four seasons: Winter, Spring, Summer, and Fall.
Which biome would be found primarily in the temperate zone?
Temperate biomes include forests, grasslands, and chaparral. Temperate deciduous forests are found in areas with continental temperate climates and temperate rainforests are found in areas with coastal temperate climates. Temperate grasslands are temperate biomes that consist mainly of grasses.
What biome is cold and dry with most of the precipitation falling as snow or ice?
For most of the year, the tundra biome is a cold, frozen landscape. This biome has a short growing season, followed by harsh conditions that the plants and animals in the region need special adaptations to survive. Tundra form in two distinct cold and dry regions.
How does agriculture contribute to groundwater depletion?
How does agriculture contribute to groundwater depletion? Agriculture contributes to groundwater depletion by using irrigation. Water is being drained for irrigational uses.
How does vegetation help reduce pollution of surface waters?
Vegetation helps to slow water movement, reducing soil erosion, which leads to less pollutants getting into our waterways. This valuable assistance is provided in several ways. Raindrops hitting leaves, stems and other plant parts get interrupted and redistributed, thereby reducing the velocity of direct soil impact.
Why are floodplains such a fertile area for agriculture quizlet?
Why are floodplains such a fertile area for agriculture? The river overflows and deposits sediments, which enrich the soil.
Are floods good for soil?
Flooding on grand scales causes soils to become water-saturated for longer than normal periods of time. This, in turn, affects soil microorganisms that are beneficial for nutrient cycling.
Do you think bacteria and fungi can play any role in recycling process?
Yes. fungi and bacteria plays an important role in recycling process.
How does the release of carbon dioxide by microorganisms benefit plant life?
How does the release of carbon dioxide by microorganisms benefit plant life? It reduces the acidity of water in soil, which increases water absorption and provides plants with necessary water.
What may be some consequences if decomposers and Detritivores disappeared or were reduced in number from ecological communities?
Imagine what would happen if there were no decomposers. Wastes and the remains of dead organisms would pile up and the nutrients within the waste and dead organisms would not be released back into the ecosystem. Producers would not have enough nutrients.
What happens when the Detritivores and the decomposers went extinct or are removed from the food chain?
If decomposers were removed from a food chain, there would be a break down in the flow of matter and energy. Waste and dead organisms would pile up. Producers would not have enough nutrients because, within the waste and dead organisms, nutrients would not be released back into the ecosystem.
What is a wetland PDF?
A wetland is an area where water covers the soil, or is present either at or near the surface of the soil all year or for varying periods of time during the year, including during the growing season.
What is the estimated value of the United States fish and shellfish industry that rely on wetland habitats enter your answer in this format 1000000?
In this region, 96% of the commercial harvest and more than 50% of the recreational catch are estuary-coastal wetland-dependent fish and shellfish. The United States commercial fisheries harvest is worth more than $2 billion annually. This harvest is the basis for a $26.8 billion fishery processing and sales industry.
Which of the following energy sources does not require waste disposal?
Hydroelectric energy does not involve waste, but does pose potential problems to waterways.
Which are non renewable energy sources quizlet?
Most non-renewable energy sources are fossil fuels: coal, petroleum, and natural gas.
What biomes have all 4 seasons?
Temperate deciduous forests are most notable because they go through four seasons: Winter, Spring, Summer, and Fall.
What is the biome called where fresh and salt water meet?
Estuaries Estuaries are regions where freshwater and ocean water mix. Life in estuaries must be adapted to this mixture of saltwater and freshwater.
