Answer: Availability of water
Explanation:
When a person is travelling from a forest ecosystem towards grassland ecosystem the number of trees gets reduced in number.
The trees are replaced by prairie grasses. This change is because of less water availability in the area having grass.
The amount of precipitation decides the type of vegetation found in that area.So the area having trees would be having more precipitation as compared to the area having prairie grass.
Answer: cofactors.
Explanation:
Epinephrine, insulin and auxins are cofactors.
Cofactors are non protein substance which activate enzymes activity by increasing the rate of chemical reaction of enzymes. They are organic molecules and they assist in enzyme activity. They exist in performing some reactions the enzymes cannot perform alone.
For example, insulin activate enzyme hexokinase which phosphorylate glucose.
Supply exceeds demand seems like to be the correct answer since it could be longer lasting.
