Answer:
it allows only some materials to pass through and leave the cell.
Food chains showcase clear picture of who is eating who. But when we try to use them to characterize entire ecological communities i.e food web, certain problems arise. For example, a species may sometimes consume numerous prey types, or be consumed by several predators at various trophic levels. To even more accurately describe these interactions, we should use a food web, a chart that demonstrates most the trophic — eating-related — relationships within an ecosystem among different species.
Arrows point from a species consumed on food chains to the creature that consumes it. Some organisms that eat species from more than one trophic stage, as shown in the food web below. Opossum shrimp, for an instance, consume both primary producers as well as primary consumers. Primary producers demonstrated with green, primary consumers with orange, secondary consumers with blue while tertiary consumers with purple.
1.Proteins. Proteins are found in the blood plasma and all over the body. The functions of protein include: repair and maintenance of body tissue, they are components of some hormones e.g. insulin, they make up enzymes, they make up transport molecules such as hemoglobin.
Lipids. These are used for energy storage and production. They provide energy for muscle and body processes.
Starch. Starch is converted into glucose for energy in the body.
Sugar . Sugar in the form of glucose is used by every cell in the body for energy.
Calcium. A mineral that is used by the body for building and keeping bones and teeth strong.
Chloride (NOT chlorine)ion. Acts as an electrolyte in the body.
Iron. Iron is an essential element of hemoglobin in the red blood cells .
Answer/Explanation:
Only the soft tissue is preserved. Normally the hard tissues are preserved(bones). But since the bones decomposed and was later filled with sediment, only the soft tissue was actually left by the animal.
