Env Science Fall Final Review

Front

What is an energy pyramid?

Back

An energy pyramid is a graphical representation that shows the flow of energy through different trophic levels in an ecosystem, illustrating how energy decreases as it moves from producers to consumers.

Front

How does cellular respiration relate to the carbon cycle?

Back

Cellular respiration releases carbon dioxide as a waste product, which is then used by plants during photosynthesis, thus connecting the two processes in the carbon cycle.

Front

Where do animals primarily obtain nitrogen?

Back

Animals obtain nitrogen primarily from the plants they eat, as plants absorb nitrogen from the soil.

Front

What adaptations do animals in a desert biome have?

Back

Animals in desert biomes have adaptations such as water conservation, nocturnal behavior, and specialized body structures to survive in low precipitation environments.

Front

What is a key difference between the phosphorus cycle and the carbon and nitrogen cycles?

Back

The phosphorus cycle does not have an atmospheric component, as phosphorus primarily cycles through soil, water, and living organisms.

Front

Define the term 'biome'.

Back

A biome is a large geographic biotic unit, a major community of plants and animals with similar life forms and environmental conditions.

Front

What role do decomposers play in an ecosystem?

Back

Decomposers break down dead organic matter, returning nutrients to the soil and making them available for plants.

Front

Explain the process of photosynthesis.

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is the significance of the nitrogen cycle?

Back

The nitrogen cycle is crucial for converting nitrogen from the atmosphere into forms usable by living organisms, thus supporting life.

Front

What is an example of a primary producer?

Back

An example of a primary producer is a plant, which produces energy through photosynthesis.
