Diagram 1 shows a food web containing eight food chains that are marked numerically, i.e. each number indicates a food chain involving the primary producer up to the apex consumer. Refer to Diagram 2 for the categories of consumers in a food chain presented hierarchically. Describe the food web through these links, drawing examples from your natural environment, in at least 150 words. Use the following additional information if necessary: Primary producers (plants) occupy the bottom level in a food chain/food web; Apex consumers (hawk in Diagram 1) occupy the top level.

The diagram illustrates the food chains carried by distinct

consumers

at different levels by producing heat individually and after the decomposition of waste and dead matter with light energy. The

biomass

is calculated in kcal per metre square per year.

Overall

,

it is clear that

light energy is the main source of the food web.

However

, the plants are the producers of

this

chain. The energy stored as

biomass

is very low for the apex

consumers

as compared to primary

consumers

. The primary level of the food web consists of insects

such

as grasshoppers, bees, butterflies, spiders, caterpillars, and so on with a

biomass

of 2000.

Also

, frogs and birds are part of secondary eaters which produces heat as well. Afterwards, the distinct kinds of snakes are

also

tertiary

consumers

which eat frogs and rabbits.

Likewise

, the top level consumer is hawk which releases waste and dead matter

while

eating snakes with the

biomass

of 2 only.
