Ecology Review #1

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 various levels of consumers.

Front

How much energy is transferred to the next level in an energy pyramid?

Back

10% of the energy is transferred to the level above, while 90% is lost as heat.

Front

What happens to energy as you move up an energy pyramid?

Back

Energy decreases as you move up the pyramid.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which plants convert solar energy into chemical energy, producing glucose and oxygen from carbon dioxide and water.

Front

What are producers in an ecosystem?

Back

Producers are organisms, like plants, that create their own food through photosynthesis and form the base of the food chain.

Front

What is cellular respiration?

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

Front

What role do producers play in a food chain?

Back

Producers are essential for the food chain as they provide energy for all other organisms (consumers) in the ecosystem.

Front

What happens if producers are removed from an ecosystem?

Back

If producers are removed, the food chain and food web will collapse, as there will be no energy source for consumers.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers (herbivores) in a food chain.

Front

Give an example of a secondary consumer in a food chain.

Back

An example of a secondary consumer is a fish that eats grasshoppers.
