Question

How does light affect the ecosystem?

Answer 1

Hint: Ecosystem is the functional unit of nature where one living organism interacts among themselves and the surrounding environment. A constant input of solar energy is the basic requirement of any ecosystem to function and sustain. Productivity is one of the components of an ecosystem.

Complete answer:
Light affects the environment in a number of ways, including energy usage, to provide energy to warm the earth’s atmosphere.
Light also affects divergent aspects of an animal’s life. Light duration affects plant flowering and animal/insect habits.
Many animals prefer to remain in the dark, while others like hydroids fail to survive in the absence of light. Sunlight is necessary for plants to grow.
The Sun is the major source of energy for organisms and ecosystems. Different producers like plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.
Without the Sun's heat and light, life doesn’t exist on this earth.

Light plays a very crucial role in plant life. All aspects of plant life like morphology, distribution, physiology, growth, reproduction, development etc. Are controlled by light.

Note:
Different characteristics of light can affect the plant in different ways:-
1. Light quality :-different wavelength of light decides its quality so as its effect. Maximum photosynthesis in blue and red light.
2. Light intensity:- It controls plant growth and makes plant life possible through photosynthesis which balances our ecosystem.
3. Light duration:- daily and yearly duration of light effects on vegetative and reproductive structure of plants..
