What is composed of several food chains in an ecosystem that intersect and depend on one another?

Food web

Step-by-step explanation:

Food chain describes how each living organism feed.

Plants are producers because the use photosynthesis to grow and provide nutrients which animals later come to consume, because animals devour plants or animals because they cannot produce their own food like plants. The animals are known as consumers.

Fungi is also a consumer because it absorbs the nutrients available from other living organisms.

Consumers are classified into three types:

1. Carnivores are organisms that feed mainly on animals



2. Herbivores who feed on plants

3. Omnivores who feed on both plants and animals.

A food web describes the relationship between various food chains and how they interact with each other in the eco system.

step-by-step explanation:

10.50 + taxes which added up to 11.50

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
