Shalnov [3]3 years ago

The skin contains layers that protect the internal parts of the body. The epidermis is the outer layer of the skin that contains cells called kertinocyte that pact together so that no bacteria can pass through the deeper layer of the skin. Aside from this protective barrier, the skin also has Langerhan cells that are part of the immune system. These cells signal the immune system to release white blood cells to protect invading harmful bacteria and other forms of infection. This is the reason why every time you scratch your skin it turns red and becomes swollen.

In 3–5 sentences, compare and contrast the flow of matter and energy in each trophic level for land-based ecosystems and marine
Mnenie [13.5K]

Answer:

Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.

Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.
