Answer 1

Answer:

those organisms that decompose the living organisms after death and change them into simpler substances are called decomposers. For example fungi, bacteria,etc. difference between herbivores and carnivore are

the animals that eat green plants are called herbivores but the animals that eat flesh of other animals are called carnivores.

examples of herbivores are cow,goat,etc but examples of carnivores are lion, tigers,etc.

Answer 2

Answer:

1. Those animals which feed on flesh of dead animals are called scavengers.eg.vulture.

2. Decomposer is an organism that decomposes or breaks down organic matter of dead organisms.Examples of decomposers: fungi, bacteria, earthworms, insects .

3. A detritivore is an organism that eats dead or decaying plants or animals as food. Detritivores include microorganisms such as bacteria and larger organisms such as fungi, insects, worms, and some crustaceans. Detritivore is a combination of the word detritus and the suffix -vore.

4. Carnivores are those animals that consume only meat of other animals. Herbivores include those animals that depend on plants or plant products for their food and nutrition. ... The herbivores have got broad and flat teeth that help them to grind and smash the food such as leaves, seeds etc.

5. The trophic level of an organism is the place it has in a food chain. A food chain is mostly made up of three trophic levels. However, some trophic levels have four trophic levels. An example is shown in the diagram.

→Primary producers which are plants that are autotrophs and belong to the first trophic level.

→Primary consumers are animals that belong to second trophic level and feed on plants. They are called herbivores.

→Secondary consumers feed on herbivores and belong to the third trophic level. They are called primary carnivores.

→Tertiary consumers feed on primary carnivores and belong to the fourth trophic level. They are called secondary carnivores
