Answer:
economic consequences
Whilst human-made changes to ecosystems have often generated large economic gains, biodiversity loss damages the functioning of ecosystems and leads to a decline in essential services, which may have severe economic consequences, particularly in the longer term.
social consequences
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, local migration and, on occasion, may even cause or exacerbate political conflict

- The question is incomplete as it does not have the option which are:
- Enzymes for the breakdown of the food are delivered to the food vacuole from the cytosol.
- Proteins for digestion of the food are made by ribosomes in the Golgi apparatus.
- The membrane of the food vacuole is derived from the cell wall.
- Proteins for digestion of the food particle were initially processed in mitochondria.
- Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm.
Answer:
Digestion of the food particle occurs in a vesicle enclosed by a membrane that separates the digestion from the cytoplasm.
Explanation:
A food vacuole is a digestive organelle present in the protozoans which contains the enzymes responsible for digestion. The food vacuole is membrane-bound organelle thus separates the food particles from the cytoplasm of the cell.
The digestive enzymes like proteases, DNases, RNases, lipase and many other enzymes digest the macromolecules and convert them to simple compounds. These nutrients are then used by the organism for the growth of the cell.
Thus, the selected option is correct.
It packages the DNA within the chromosome and it helps with DNA replicating (cell division).
