Answer:
5)Ecosystem is made up of living and nonliving things. An ecological pyramid is composed of producer, herbivores, carnivores. Producers occupy the first trophic level. They use solar energy to synthesize their food by the process of photosynthesis. Herbivores occupy the second trophic level. They are also called as primary consumers. They feed on producers. The third trophic level is occupied by the carnivores which feed eat herbivores. They are also called as secondary consumers.
6)Plants are referred to as producers because they produce energy-rich carbon compounds using the Sun's energy.
7)Primary consumers are herbivores, feeding on plants. Caterpillars, insects, grasshoppers, termites and hummingbirds are all examples of primary consumers because they only eat autotrops.
8)There are two types of a food chain.
(i) Detritus food chain always starts with the dead organic material. Food energy pass into decomposers and detrivores, which are further consumed by smaller carnivores, like maggots, which in turn become food for larger carnivores, like a frog and further to snake and so on.
(ii) A grazing food chain always starts with the living green plants and goes to herbivores and on to carnivores. It is directly dependent on a solar radiation. This type of chain depends on autotrophic energy capture and the movement of this energy to herbivores. Most of the ecosystems in nature follow this type of food chain.
A food chain is a linear sequence which represents who is eating who. Here, organisms of higher trophic level derive its nutrients from organisms of a lower trophic level. A food web is a network of food chains, which are interconnected at different trophic level. More the number of cross-connections between different food chains, more complex will be the food web and greater will be the stability of the ecosystem.

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.
10)There are three biotic components of an ecosystem, namely producers, consumers and decomposers. Decomposers break down dead plants and animals and convert them into simpler organic molecules which are released in the atmosphere. They play crucial role in an ecosystem. If they were not present in an ecosystem, the nutrients would not get recycle and plants would not get essential nutrients. Also, in absence of decomposers, the dead matter and waste would pile up.

hope this will help u
Answer:
5. Trophic level of herbivores in the food chain is called primary consumers.
6. Plants are called producers because they are autotrophs ( living organisms that prepare their own food ) and the primary consumers ( herbivores ) eat the plants ( producers ) and the secondary consumers ( carnivores or omnivores ) eat the primary consumers, therefore plants are called producers.
7. Name of two primary consumers -
Deer, Rabbit
8. There are two types of food chain. They are grazing food chain and detritus food chain.
Grazing food chain - It is a type of food chain in which energy at the lowest trophic level is acquired via photosynthesis. The grazing food chain begins with producers like green plants, who create their own food through the process of photosynthesis and later move from herbivores to carnivores.
9. Consumers in a food chain are living creatures that eat organisms from different population.
Within an ecological food chain consumers are categorized into -
Primary consumers,
Secondary consumers and
Tertiary consumers.
10. The role of decomposers in an ecosystem is to keep the ecosystem clean by decomposing the dead animals and plants, and thereby again adding nutrients to the soil, and those nutrients are used by the plants..
