- Over exploitation of the species
- Pollution that threatens the existence of the species
<h3>What are endangered species?</h3>
Endangered species are those species that are facing the threat of extinction sometimes owing to severe habitat loss or some other factors.
We must note that these characteristics that make it difficult for endangered species to rebound;
- The habitat is significantly changed
- Over exploitation of the species
- Pollution that threatens the existence of the species

It is the same as creating more pests or setting up dominant species which upset the ecological food pyramid leading to decimation of trophic levels or predators and energy cycling. Fishes feed on microscopic algae and animals the primary base of the food chain in water, if they are not checked they will choke the rivers and oceans causing toxic waters. Fish feed to contain them, in the process they grow and increase in numbers but their population is checked by bigger fishes and so on till it reaches a top predator which is usually a large animal.
Answer:
These gel cubes can be thought of as representing individual cells. As the cubes interact with their surroundings based on the amount of surface area and volume they have, the efficiency movement of substances in and out of cells depends on the two attributes as well. Greater surface area will mean more efficient rates of diffusion, which implies a smaller surface area to volume ratio is ideal for a biological cell.
