Those organisms which join the food chain are termed as trophic levels
There are four trophic levels:
(i) First trophic level – Producers (Plants)
(ii) Second trophic level – Primary consumers.
(iii) Third trophic level – Secondary consumers.
(iv) Fourth trophic level – Top consumers.
Plants–> Rabbit–> Wolf–> Tiger
In the above food chain plants are producers and represents the first trophic level.
Rabbit is the primary consumer i.e. herbivorous animal and represent the second Trophic level.
Wolf is the secondary consumer and represents the third trophic level.
Tiger is the top consumer and represents the fourth trophic level.
Non-biodegradable substances would affect the environment in following two ways- (i) Non- biodegradable substances may cause soil pollution and water pollution. (ii) If non-biodegradable substances remain in fertile soil or land than it becomes barren.
Non-biodegradable substances would affect the environment in following two ways-
(i) Non- biodegradable substances may cause soil pollution and water pollution.
(ii) If non-biodegradable substances remain in fertile soil or land than it becomes barren.
Biodegradable substances would affect the environment in following two ways- (i) These substances decomposed by the action of micro-organisms that cause foul smell. (ii) The rotting biodegradable wastes act as breeding ground for insects which may cause diseases to living organisms.

Biodegradable substances are those substances on which micro-organisms like bacteria or decomposers act and break down these substances into simpler compounds, example of Biodegradable substances are dead remains of plants and animals and their waste products, paper etc. But on some compounds like pRead more
Biodegradable substances are those substances on which micro-organisms like bacteria or decomposers act and break down these substances into simpler compounds, example of Biodegradable substances are dead remains of plants and animals and their waste products, paper etc.
But on some compounds like plastics and metals, micro-organisms do not act to decompose them and these compounds are known as non-biodegradable compounds.
What is the role of decomposers in the ecosystem?
Decomposers act as cleansing agents of environment as they decompose the dead bodies and dead parts of plants and animals and clean the environment.
