Question

hive differences between the following:
1. Food chain and Food Web
2. Producers and Consumers
3. Herbivores and Carnivores
4. Decomposers and Scavengers​

Answer 1

Explanation:

1.food chain and food web

Ans:-

The Food Chain can be said as the single straight pathway, through which there is a flow of energy from the lower trophic level to the higher trophic level. Food Web can be defined as the complex interconnection of numerous food chains through which the energy flow in the ecosystem.

Food Chain consists of only one straight chain, while food web has numbers of interconnected food chains.

In comparison to the food web, there is a lot of instability in the food chain, and this is due to increasing number of separate and confined food chains. Whereas in food web there is stability and it increases due to the presence of the complex food chains.

As in food chain, there are 4-6 trophic levels only of different species, and any disturbance at any level may disturb the whole chain. On the other hand in food web there in the involvement of numerous trophic level of the different population of a species and so it does not affect the food web if there is a removal of any group of organisms at any trophic level.

In the food chain usually, member of higher trophic level depends or feed upon the single type of organisms of the lower trophic level.

On the contrary, in the food web, the members of higher trophic level depends or feed upon many different types of the organism of the lower trophic level.

Answer 2

Explanation:

food chain and web

1. food chain is small , 3 or 4 organisms while food web is larger, it consists of several food chains linked together in an ecosystem
2. in a food chain , an animal only eats one kind of organism, in food web, animal can have multiple preys

Producers and consumers

1. Producers prepare their own food by process of photosynthesis , while all consumers depend on producers for food, directly or indirectly
2. Producers are green plants and some bacteria while consumers all other organisms

Herbivores and carnivores

1. Herbivores feed on plants for food while carnivores feed on other animals
2. Herbivores do not depend on carnivores but carnivores depend on herbivores for food
3. Giraffe - herbivores , Lion - carnivore

Decomposers and scavengers

1. Decomposers are bacteria which act on dead and decaying organic matter and convert them to inorganic substances , while scavengers are animals which feed on leftover food
2. Decomposers give nutrients back to soil while scavengers clean the environment
3. Bacteria - decomposers ,vulture - scavengers
