Food webs either start with producers or with producers in

Food webs either start with producers on land or with producers in water.

Explanation:

A food chain or a food web will always start with a producer and always end with a type of consumer. This is because producers are organisms which have the ability to make their own food. They are mostly plants or other producers like algae. Both aquatic and land food chains or food webs will start with a producer. An aquatic food web will generally start with a producer present in water. A land food web will mostly start with a producer from the land.

Food webs either start with producers on top or with producers in the middle.

Explanation:

One type of organism or species in an ecosystem happens to be the same food source for other types of consumers. The producers represent the first trophic level in an ecosystem that are sources of energy for all other living organisms. The different food chains that exist form a complex network called a food web.

sandy loam should be dominated by the sand. as the amount of sand increased, the amount of slit needed to anchor the plants' roots to the sand will also be increased. even though the amount is very little, 10% part of clay is still necessary for proper oxidation.
