Question

17)
The food chain in a community actually represents a stepwise transfer of food and the energy
contained in food. The producers are eaten up by herbivores .Herbivores are consumed by
carnivores. There is a continuous transfer of energy from one trophic level to the
next. Materials like water,carbon,and nitrogen are present in the bodies of organisms return
to the soil by the action of decomposers which are available for the plants once again.
17 i)
What form of energy flows through a food chain?
17 ii)
Define the process by which plants produce the food.
17 iii)
What is 10 percent law?
17 iv)
Name some decomposers present in the ecosystem?
17 v)
Why the flow of energy in a food chain is uni directional?​

Answer 1

Answer:

1

Explanation:

1- The food chain begins with producers, organisms such as green plants, that can make their own food. Through photosynthesis, producers convert solar energy to chemical energy, energy in the chemical bonds of the food

2- The process by which plants make food is named as photosynthesis. Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis requires sunlight, chlorophyll, water, and carbon dioxide 

3- According to 10 percent law, 90% of the energy captured from the previous trophic level is lost as heat to the environment and only 10 percent is made available to the next trophic level. ... A pyramid of energy depicts the energy flow form one trophic level to another trophic level in the food chain.

4- Most decomposers are microscopic organisms, including protozoa and bacteria. Other decomposers are big enough to see without a microscope. They include fungi along with invertebrate organisms sometimes called detritivores, which include earthworms, termites, and millipedes.08-Jan-2020

5- The flow of energy in food chains is unidirectional. The energy which passes to the herbivores does not come back to the autotrophs. ... This energy is no longer available to the previous trophic level. Thus, the flow of energy in a food chain is unidirectional.
