Answer:
The correct answer will be- Keystone species
Explanation:
The structure of a community is largely determined by the number of species present in the community called species richness and the species diversity.
The species which can play an important role in determining the community could be of two types the foundation species and keystone species.
The species which directly influence the diversity of a community irrespective of their number and abundance is known as the keystone species.
In the given question since the question has discussed the species which disproportionately influence the diversity of the community is known as keystone species.
Thus, keystone species is the correct answer.
Answer: It reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds.
Hydrolysis is a chemical process in which a water molecule is inserted.
In light-based reaction, which occurs in the thylakoid layer, chlorophyll absorbs energy from the sun and converts it into chemical energy through water. Light-dependent reactions release oxygen to water hydrolysis as a by-product.
