Summary Introduction

Introduction:

There are various characteristics of the communities like their diversity and also their species feeding relationships.

Answer to Problem 1TYU

Correct answer:

The feeding relationship among the species in a community determines the trophic structure of the community. Therefore, option (D) is correct.

Explanation of Solution

Reason for the correct statement:

Trophic level refers to the position that a specific organism takes place in the food chain. The structure of trophic describes the relationship of feeding amongst the organisms. It is thus, also known as the food web or food chain.

Option (D) is given as “trophic structure”.

“The feeding relationship among the species in a community determines the trophic structure of the community”, it is the right answer.

Hence, option (D) is correct.

Reasons for the incorrect statements:

Option (A) is given as “secondary succession”.

It is one of the types of ecological succession. It refers to the change or destruction that occurs in a habitat due to any natural disaster. So, it is a wrong answer.

Option (B) is given as “ecological niche”.

It shows the role and position of a species with the environment. So, it is a wrong answer.

Option (C) is given as “species richness”.

It refers to the measurement of species diversity that is the number of species variety in a community. So, it is a wrong answer.

Hence, options (A), (B), and (C) are incorrect.

Conclusion

The trophic structure determines the feeding relationship among the species in a community.

What are biofertilizers and mention the significance
PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen.     How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans?   Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.
