Biosphere (Biodiversity)

Question 1

Identify and define the levels of organisation within the biosphere

Biodiversity

Answer 1

1. Species: An individual living thing of a kind - can breed to produce fertile offspring.
2. Population: A group of organisms of the same species living in the same area.
3. Community: All the populations of different species that interact within a specific area.
4. Habitat: A location where an organism lives, recides, or exits.
5. Ecosystem: A community interacting with the non-living components of their environment (air, water, and soil).
6. Biosphere: The global ecosystems that includes all living beings.

Question 2

The Producers get their energy from the sun using photosynthesis, producing 2,000 kcal/m²/year. Then, the Primary consumers eat the producers, trensferring 10% of energy made. Next, the Secondary Consumers eat the primary consimers, again, only trensferring 10% of the energy. And finally, the Apex Preditors eat the secondary consumers, only transferring 10% od the energy, finishing with 2 kcal/m²/year

Question 3

Define biodiversity

Answer 3

The variety of plant or animal life in the world or in a particular habitat, with a high level in what is considered to be important or desirable.
.

Question 4

Explain the importance of biodiversity for all life on Earth

Answer 4

biodiversity is important because it ensures healthy and well-functioning ecosystems, which are critical for a productive environment. Intact ecosystems provide habitat for native plants and animals and offer vital ecosystem services such as clean drinking water, fertile soils, and productive oceans for food production

Question 5

Describe how biodiversity is impacted (i.e., increased, decreased)

Extra: What decreases boidiversity

Answer 5

Biodiversity is impacted by natural and human-induced factors.
It is increased by:
- genetic change
- evolution

It is decreased by:
- habitat degradation
- population decline
- extinction

The decreasing is often driven by:
- land use changes
- climate change
- invasive species
- pollution.

Question 6

Identify and compare direct and indirect drivers of biodiversity, including human impact

Answer 6

• Direct: Habitat destruction, overhunting, pollution, invasive species.
• Indirect: Climate change, economic development, agricultural practices.
