Q5. What is the trophic level of herbivorous
consumers in the food chain?
Q.9 What are consumers? How are they categorised?
Q12 Discuss how the plant are essential for animals ?
Answers
Answer:
5.The trophic level of an organism is the position it occupies in a food web. A food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as plants, can move to herbivores at level 2, carnivores at level 3 or higher, and typically finish with apex predators at level 4 or 5. The path along the chain can form either a one-way flow or a food "web". Ecological communities with higher biodiversity form more complex trophic paths.
9.In an ecosystem, there are basic 3 biotic components. These are producers, consumers and decomposers. In a food chain, consumers are categorized into 3 categories, namely herbivores, carnivores and omnivores. Primary consumers are herbivores. They feed on producers, or plants. Examples include zebra, giraffe, cow. Secondary consumers are carnivores. They feed on primary consumers for food. Examples include lion, tiger. Omnovores are those consumers which feed on both plants (producers) and animals (primary consumers). Examples include bear, chicken.

Animals and humans depend on plants for many things, and without plants, there could be no life on Earth. Here are some point to consider:
Animals and humans depend on plants for many things, and without plants, there could be no life on Earth. Here are some point to consider: 1. Plants are the primary producers. They are the only organisms that can make their own food. Animals, who are incapable of making their own food, depend on plants for their supply of food.

Animals, who are incapable of making their own food, depend on plants for their supply of food. 2.The oxygen that animals breathe comes from plants. Through photosynthesis, plants take energy from the sun, carbon dioxide from the air, and water and minerals from the soil. They then give off water and oxygen. Animals then use oxygen process called respiration. Respiration is the process used by organisms to release energy from food, and carbon dioxide is given off.

The plants provide food, shelter from weather (rain, sun), nesting place, sleeping ground and hideout from predators. For example: Different animals live in different parts of the rainforest. Scientists divide the rainforest into zones based on the living environment.
