All organisms perform whether or not oxygen is present. a). glycolysis b). aerobic respiration c). photosynthesis d). none of the above

Glycolysis

Explanation:

Glycolysis is an universal process which takes place in all the organism from bacteria to humans. It can occur whether oxygen is present or not. It is the first step of cellular respiration that takes place in cytosol.

During glycolysis, breakdown of the glucose into pyruvate occurs with the formation of two energy molecules of ATP and two NADH molecules.

Thus, the correct answer is option (A).

1. a host loses nutrients to a parasite

2. a parasite only benefits when the host is alive (cause if the host dies the parasite dies with it )

3. producers to consumers

4. the tapeworm is a parasite

5. they convert energy from the sun (photosynthesis)

6. sunflower-robin (i think im 80% sure)

7. producer

8. consumer

9. prey

10. fresh water snails ( cause the green algea is the producer and the snails are the primary consumers and the small fish consumer so is the big fish)

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
