which statement best explains the decrease in energy avaliability in a food chain

Answers

Answer 1

The statement that best explains the decrease in energy availability in a food chain is D. Some energy in each trophic level is used for life processes.

What is food chain?

A food chain is a network of links in a food web that runs in a straight line from producer organisms to an apex predator, detritivor, or decomposer species. A food chain also demonstrates how organisms are connected to one another by the foods they consume.

A food chain's levels correspond to several trophic levels. The flow of nutrients and energy through an ecosystem is described by a food chain. Energy is first produced by plants at the most fundamental level, and then it is used by higher-level species like herbivores.

The table shows the results of a research study. During the study, the plants were kept in greenhouses where light exposure was
strictly regulated. Each group contained 50 plants of one species and maturity. Based on the table, what was the most likely source of
error?

Answers

The most likely source of error in the research study is sampling error. Sampling error occurs when the sample chosen to represent a population is not truly representative of the population.

How to explain the information

In this case, the sample size of 50 plants in each group is relatively small, and it is possible that the plants in the sample were not representative of the entire population of plants. This could lead to the results of the study being biased.

There are a few things that could have caused the sample to be biased. For example, the plants in the sample may have been selected from a particular location, which may have had different environmental conditions than the rest of the population. Additionally, the plants in the sample may have been planted at different times, which could have led to differences in their growth rates.
