Chapter 44, Problem 1TY

Summary Introduction

Introduction:

A group of populations of animals and plants lives within the specific geographical area under the same environmental conditions. For example, soil containing bacteria, forest of trees, etc. A community has a wide variety of uses.

Answer to Problem 1TY

The correct answer is option (d) low species richness and high abundance.

Explanation of Solution

Explanation/justification for the correct answer:

Option (d) low species richness and high abundance. High abundance species are more likely to have offspring. Later, these offspring are more likely to inhabit a new area of the ecosystem, then a less abundant species. So, this is the correct option.

Explanation for incorrect answer:

Option (a) low abundance and high species richness.If there are low number of species, then species richnes cannot be high. So, this is an incorrect option.

Option (b) high stability. If the species in a geographical area is high in stability then no interaction would occur between more species or individuals. It also decreases the plant biomass. So, this is an incorrect option.

Option (e) high species diversity. High species diversity does not provide stability in the ecosystem. In spite of decades of research, the question of making system balance is largely unanswered. It decreases plant biomass. So, this is an incorrect option.

Option (f) high abundance and high species richness. High abundance and high species richness lead to an increase in the high competition which may cause the extinction of species or individuals. So, this is an incorrect option.

Conclusion

In low species richness, different species also exhibit because of high abundance. in low species richness, there would be an interaction between different species. Hence, the correct answer is option (d) low species richness and high abundance.
