Afood chain is a model that represents how energy and matter are transferred through an ecosystem. typically, a food chain has five or fewer links because a. no organism exists that eats more than five types of food. b. there are only three categories of organism—producers, consumers, and decomposes. c. the amount of energy available decreases with the addition of each link. d. humans are the top predators and are always the fifth link.

Option C

Explanation:

The food chain is a model which is used to show the inter linking of the animals with each other and interdependence of animals and their food on each other.

There are only fewer animals in a food chain because the energy decreases as we up in the the food chain. If there is any other link added to the food chain the energy will decrease more. Only 10 percent of the total energy is transferred from one level to another.

So, because of this reason only fewer levels are found in the food chain.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
