A
The health of the ecosystem increases.
B
The health of the ecosystem decreases.
C
The health of the ecosystem remains the same.
D
The ecosystem cannot survive.
Explanation: 

Detailed explanation-1: -Biodiversity loss can have significant direct human health impacts if ecosystem services are no longer adequate to meet social needs. Indirectly, changes in ecosystem services affect livelihoods, income, local migration and, on occasion, may even cause or exacerbate political conflict.

Detailed explanation-2: -Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).

Detailed explanation-3: -Scientists have long hypothesized that biodiversity is of critical importance to the stability of natural ecosystems and their abilities to provide positive benefits such as oxygen production, soil genesis, and water detoxification to plant and animal communities, as well as to human society.

Detailed explanation-4: -Biodiversity, or the variety of all living things on our planet, has been declining at an alarming rate in recent years, mainly due to human activities, such as land use changes, pollution and climate change.

Detailed explanation-5: -Biodiversity loss and ecosystem change can increase the risk of emergence or spread of infectious diseases in animals, plants and humans, including economically important livestock diseases, zoonotic outbreaks and global pandemics.
