What characteristic sets heterotrophs apart from autotrophs?

Heterotrophs obtain food from consuming other living or once-living things.

Heterotrophs can be classified only as mammals.

Heterotrophs use energy from the sun to make their own food.

Heterotrophs obtain food through the process of photosynthesis.

How can photosynthesis be related to cellular respiration?

What's produced (made) by one is needed (the reactants) for the other

They both produce the same products

They both have the same reactants (need the same things)

These 2 processes have nothing in common

tiny holes in the leaves of a plant that allow gases to enter or leave the plant

a plant part that carries out photosynthesis to make food for the plant

the process in which plants use energy from the sun to make their own food

In which way are photosynthesis and cellular respiration different?

Photosynthesis used carbon dioxide, while cellular respiration produces carbon dioxide.

Cellular respiration stores ATP, while photosynthesis releases ATP.

Cellular respiration produces oxygen, while photosynthesis uses oxygen.

Photosynthesis releases energy, while cellular respiration stores energy.

What is the correct equation for cellular respiration?

6O 2 + C 6 H 12 O 6 -> 6CO 2 + 6H 2 O + Energy

6O 2 + C 6 H 12 O 6 + Energy -> 6CO 2 + 6H 2 O

6CO 2 + 6H 2 O -> 6O 2 + C 6 H 12 O 6 + Energy

6CO 2 + 6H 2 O + Energy -> 6O 2 + C 6 H 12 O 6

Why are most food chains and food webs limited to three to five trophic levels?

There is insufficient energy to support more trophic levels.

Most ecosystems have insufficient space to support the increased number of organisms that more trophic levels would require.

The nutritional quality of existing biomass decreases with increasing trophic level.

The higher the trophic level, the larger the organism; the large the organism, the less likely it will be prey.

How does carbon enter the living portion of an ecosystem?

It is taken in by autotrophs for use in photosynthesis.

It is taken in through plant roots.

Animals breathe it in and make it into biomass.

An ecosystem is a community of organisms interacting with their physical environment. 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.

They provide most of the energy to consumers.

How does the carbon in grass become part of a lion?

The carbon ends up in the lion's food chain.

Carbon from grass doesn't end up in a lion.

The lion breathes in carbon given out by the plant
