Back

Mitochondria

Front

Which of the following is NOT a producer? Oak tree, Algae, Rabbit, Grass

Back

Rabbit

Front

What is the main purpose of cellular respiration?

Back

To extract energy from food

Front

Relationship between photosynthesis and cellular respiration in terms of inputs and outputs.

Back

Photosynthesis converts carbon dioxide and water into glucose and oxygen, whereas cellular respiration converts glucose and oxygen back into carbon dioxide and water.

Front

How do decomposers contribute to the cycling of matter in an ecosystem?

Back

They convert dead matter into usable nutrients.

Front

Why is photosynthesis important for life on Earth?

Back

It produces oxygen and food.

Front

How does energy flow through living things, starting with the sun?

Back

Energy flows from the sun to producers, then to consumers, and finally to decomposers.

Front

Difference between aerobic and anaerobic respiration:

Back

Aerobic respiration requires oxygen and produces much more ATP (around 38 ATP per glucose) whereas anaerobic respiration does not require oxygen and produces much less ATP (around 2 ATP per glucose).
