Answer:
E) reduce the number of primary producers
Explanation:
The primary producers are the ones that are the basis of any ecosystem on the planet. They have the ability to produce food for themselves, thus they are autotrophs, and they are the ones that are the food source for the primary consumers. With reduction of the primary producers the whole ecosystem will instantly feel the effects. The primary consumers will be left without food, meaning that they will start to die out. The dying out of the primary consumers will lead to dying out of the secondary consumers, and their dying out will result in the dying out of the predators, or rather the tertiary consumers. The end result will be a collapse of the ecosystem, which will then be inhabited by other organisms, first through the primary succession, and then through the secondary succession, resulting in a new and different ecosystem.
Answer:
The correct answer is option A. "Hormone receptors evolved later than many of the hormones with which they now interact".
Explanation:
It is false to affirm that hormone receptors evolved later than many of the hormones with which they now interact. There are multiple scientific studies that support the theory that receptors and ligands evolve at the same time in what is known as "synchronous birth". Receptor and ligand interactions are key components in the processes of living organisms, therefore, it they should evolve together in order to be functional.
