Assignment: Populations Exploration

Choose two of the following biomes:
• desert
• tropical rainforest
• deciduous forest
• Arctic tundra
• taiga
• tropical savannah

Choose one population of organisms from each biome (for example, the musk ox from the Arctic tundra and the red kangaroo from the desert) and answer the following questions about each population in each of the biomes you have chosen.

Biome1:

Organism 1:

1. In what type of ecosystem can this population be found?

2. How might this population suddenly increase? How might this affect the ecosystem?

3. What might happen to the ecosystem if this population were removed?

Biome 2:

Organism 2:

1. In what type of ecosystem can this population be found?

2. How might this population suddenly increase? How might this affect the ecosystem?

3. What might happen to the ecosystem if this population were removed?

Answer no 1)

Biome1: Desert

Organism 1: Camels

1) This population can be found in an ecosystem which is dry and do not have grass or much plants. Large trees are unable to grow in such a land. Also, the water available is limited in such a land.

2) The population of camels might suddenly increase if more water and food becomes available on this land. Camels feed on grass, grains etc. We can increase the supply of these to increase its population.

3) If the population of the camels is removed, then the desert ecosystem will become unstable.

Answer No 2)

Biome 2: Taiga

Organism 2: Fox

1) This population is usually found in forest where there is abundant supply of different species of animals and plants. Also, needle leaved trees are more abundant in this biome.

2) The fox has a number of preys in which it can feed. Foxes can fees on birds, other mammals, some reptiles etc. If the population of a prey is increased, the population of the foxes might also increase. This will cause a disturb in an stable ecosystem.

3) If the population of foxes were removed, then the population of the prey organisms will increase. The ecosystem will become unstable.

the reason the two sea urchins don't compete with each other for food, resources, etc. is because the urchins have adapted to the environment but they have also adapted to each other. this is most likely because the genes of the sea urchins.
