Answer:

Final answer:

The factor of interest in an experiment is called the Variable.

Explanation:

In an experiment, the factor of interest is called the Variable. The variable is the specific aspect or condition that is being tested or manipulated in an experiment to determine its effect on the outcome.

For example, if you are experimenting to test how different amounts of fertilizer affect plant growth, the variable would be the amount of fertilizer applied. In this case, the amount of fertilizer is the factor of interest that is being studied.

Therefore, the correct answer is d. Variable.

If there were 2,000 units of biomass among the primary producers of a food chain, how much biomass would be expected among the tertiary consumers in that same food chain? 200 units 2 units 20 units 100 units 1,000 units

Answers

Answer:

2 unit

Explanation:

According to the 10% law, the transfer of biomass energy from one higher trophic level to lower trophic level is only 10%.

Primary(Producer)→Primary consumers→secondary consumers→tertiary consumers.

that is 2000→200→20→2

note: only 10% of the total biomass is received by the next trophic level.

therefore tertiary consumers will receive 2 units of biomass.
