What is the name given to the region where sea meets land?
The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

What level of ecology is concerned with the adaptations of individuals?
Researchers studying ecology at the organismal level are interested in the adaptations that enable individuals to live in specific habitats. These adaptations can be morphological, physiological, and behavioral.
What level of ecology is concerned with groups of individuals of different species Group of answer choices?
Community: A biological community consists of all the populations of different species that live in a given area. Community ecologists focus on interactions between populations and how these interactions shape the community.
Which of these organisms convert atmospheric nitrogen gas to a form that can be utilized by plants?
Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. Ammonia, nitrites, and nitrates are all fixed nitrogen and can be absorbed by plants.
What are open oceans called?
The pelagic zone, also known as the open ocean, is the area of the ocean outside of coastal areas.
What energy is needed by photosynthetic organisms during the process of photosynthesis?
the Sun During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
What reactants are involved in photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Which of these conditions would most likely cause a decrease in the population of any species?
Habitat loss is the leading known cause of population decline. A species is also classified as vulnerable if its population has declined at least 30 percent and the cause of the decline is not known.
What level of ecology is concerned with the biotic and abiotic aspect of an environment?
The broadest most inclusive level of organization is the biosphere. This includes both biotic and abiotic components of the earth and the part of the atmosphere that supports life.
What level of ecology is concerned with a group of individuals of the same species living in the same area?
What is a population? a group of individuals of the same species living in a particular geographic area. What is a community? Consist of all the organisms that inhabit a particular area.
Which level of ecology is concerned with both the biotic and abiotic aspects of the environment?
The broadest most inclusive level of organization is the biosphere. This includes both biotic and abiotic components of the earth and the part of the atmosphere that supports life.
Why is it that nitrogen is often a limiting plant nutrient despite the fact that the atmosphere is 80% nitrogen gas N2 )?
Why is it that nitrogen is often a limiting plant nutrient, despite the fact that the atmosphere is 80% nitrogen gas (N2)? A. Because nitrogen gas converts easily into carbon dioxide.
Why is nitrogen abundant in the atmosphere?
Nitrogen is not stable as a part of a crystal lattice, so it is not incorporated into the solid Earth. This is one reason why nitrogen is so enriched in the atmosphere relative to oxygen.
What is estuary in geography?
An estuary is a partially enclosed, coastal water body where freshwater from rivers and streams mixes with salt water from the ocean. Estuaries, and their surrounding lands, are places of transition from land to sea.
Which ocean is on the eastern coast of north and South America?
Atlantic Ocean, body of salt water covering approximately one-fifth of Earth's surface and separating the continents of Europe and Africa to the east from those of North and South America to the west. The ocean's name, derived from Greek mythology, means the “Sea of Atlas.” It is second in size to the Pacific Ocean.
What are the essential factors for photosynthesis?
3 factors necessary for photosynthesis to take place are: 1. Presence of sunlight 2. Presence of chlorophyll 3. Presence of water and carbon-dioxide
- Presence of sunlight.
- Presence of chlorophyll.
- Presence of water and carbon-dioxide.
What does chlorophyll do in photosynthesis?
Chlorophyll's job in a plant is to absorb light—usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose, a type of sugar.
What is needed in photosynthesis?
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
What are the limiting factors that affect population growth?
In the natural world, limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations.
Which of the following is a factor that limits population growth?
Factors that decrease population growth can be defined as environmental stress including limitations in food, predation, and other density-dependant factors (Sibley & Hone 2002). However, many sources of environmental stress affect population growth, irrespective of the density of the population.
What are the two major factors determining the distribution of terrestrial biomes?
The two major factors that determine the distribution of terrestrial biomes are precipitation and temperature.
What level of the biological organization makes up the group of organisms of the same species?
population A population is a group of organisms belonging to the same species that live in the same area and interact with one another. A community is all of the populations of different species that live in the same area and interact with one another. A community is composed of all of the biotic factors of an area.
Which level of ecological study includes species interacting each other and with the physical environment?
At the organismal level, ecologists study individual organisms and how they interact with their environments.
What is the lowest level of organization to include both biotic and abiotic factors?
Generally, the ecosystem is the lowest level of organization that is considered to include nonliving (abiotic) factors. So that would mean that ecosystems, biomes, and the biosphere include abiotic factors. The traditional levels of organization are as follows: Biosphere.
Why is nitrogen the most limiting nutrient?
Although nitrogen is incredibly abundant in the air we breathe, it is often a limiting nutrient for the growth of living organisms. This is because the particular form of nitrogen found in air—nitrogen gas—cannot be assimilated by most organisms.
Why is phosphorus a limiting nutrient?
Phosphorus is usually considered the “limiting nutrient” in aquatic ecosystems, meaning that the available quantity of this nutrient controls the pace at which algae and aquatic plants are produced. In appropriate quantities, phosphorus can be used by vegetation and soil microbes for normal growth.
Which is the most abundant gas in our atmosphere that Cannot be Utilised by plants?
Earth's atmosphere contains a huge pool of nitrogen gas (N2). But this nitrogen is “unavailable” to plants, because the gaseous form cannot be used directly by plants without undergoing a transformation.
What is the most abundant element in the atmosphere?
nitrogen Gases. The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%.
Why Rift Valley rivers form estuaries?
Whereas Estuary is formed by those rivers which have the shortest catchment area, flows from rift valley and drains its water directly to the sea or ocean and any other form of the watercourse. The old civilizations were formed along river valleys and deltas due to its fertility.
