Question

In a climax community
A. Size of individual is small
B. Food chain and food web is complex
C. Efficiency of energy use is low
D. Ecological niches are few generalized compared to adjoining communities

Answer 1

Hint:- : Various components arrange together to form the ecosystem. The terms are species, which are constituted by various individuals. More than one species together tend to constitute the population, which then form the communities. The communities made up from different populations result in the formation of the biome. The biome is the largest unit of ecology.

Complete step-by-step solution:- A climax community is described as a biological community of living organisms. It is formed through the process of ecological succession. The endpoint of ecological succession is a climax community. It remains unchanged until destruction that is caused by human activity or nature, such as fire or any other human interference. It is an equilibrium stage of ecological succession.
The equilibrium occurs because the climax community is made up of those species that are best adapted to average conditions in that particular area.
The food chain and food web become complex in a climax community because the complex network of animal’s feeding relations is aggregated.
Thus, the correct option is (B). The food chain and food web are complex.

Note:-
A complex interaction network that is formed by the feeding relationships among various organisms in an ecosystem is known as a food web. In a food web, basal species commonly include plants and algae. These are known as autotrophs because they can prepare food with the help of sunlight and chlorophyll.
Food chains in an ecosystem refer to the sequential or stepwise transfer of energy and nutrients present in food from one organism to another. Organisms in each step of the food chain are represented with the help of trophic levels.
At each of these trophic levels of a food chain, the organism utilizes a large amount of energy to maintain itself, and some is lost as heat.
