Question

Which of the following states of an ecosystem helps it to avoid changes?
A. Homeostasis
B. Shortage of components
C. Deficiency of light
D. Imbalance

Answer 1

Hint: An ecosystem is a place where both biotic and abiotic components interact with each other. The state that helps it to avoid change is a relatively stable internal state that persists despite changes in the world outside.

Complete answer: Homeostasis is the state of an ecosystem which helps it to avoid changes. Homeostasis is a self-regulating process. In this, any biological system maintains stability by adjusting to the conditions which make their survival optimum or in other words, it is the internal ability to maintain the number of species or population in an ecosystem by introducing predation, competition, etc. as per the requirement in the ecosystem. If an organism shows homeostatic control, it means that the organism has the tendency to resist the change. Moreover, the organism has the ability to remain in an internally stable state. There is a particular range within which an organism can tolerate or can maintain the internal body state and this range is called the homeostatic range. Ecosystem homeostasis is all about equilibrium. In real ecosystems, nothing is perfectly balanced. So, an ecosystem in equilibrium is said to be in a relatively stable state.
Hence, the correct answer is option A.

Note: Imbalance occurs in an ecosystem by natural means or by human activity. When an imbalance occurs in the ecosystem, it moves from stable to unstable state due to interruption. Ecological interruption can also occur if a new species is introduced or withdrawn.
