Explanation:
Answer:
phospholipids, sterols, and triglycerides
Explanation:
Phospholipids make up the outermost layer of cells in the bodies of both animals and humans. They create a protective layer around the cells to help maintain them.
Sterols are a subset of steroids, a type of hormone.
Triglycerides are the fats and oils that you are familiar with in foods. This type of lipid can be saturated or unsaturated, which is part of what makes them solid or liquid, respectively, at room temperature.
A population decrease in primary producers would affect the ecosystem negatively because everyone who ate the primary consumers would have a lack of food.
Answer:
Proteins and phospholipids make up most of the membrane structure. The phospholipids make the basic bag, while the proteins are found around the holes and help move molecules in and out of the cell.
