Ecology and Biodiversity

What is the difference between biotic and abiotic?

• Biotic are non-living things

• Abiotic are living organisms

• Biotic is life,
  Abiotic is non-living

• Biotic is non-living, Abiotic is living

A rain forest ecosystem is characterized by high biodiversity and a warm/rainy climate. How might this impact the ecosystem's sustainability if the ecosystem is damaged by a catastrophic event?

• The ecosystem, because it has few plant and animal species, will experience low sustainability, not allowing it to recover

• The ecosystem, because it has many plant and animal species, will experience high sustainability, allowing it to recover

• Biodiversity does not have an impact on an ecosystem's sustainability

Sustainability refers to

• how many species are present in an ecosystem

• when a species goes extinct

• how long a species lives

• the ability to maintain ecological process over long periods of time.

What is true about sustainability?

• Having a small number of species increases biodiversity

• Sustainability is how organisms change over time

• Sustainability is how much rainfall and sunlight an ecosystem receives

• The more different types of species you have (biodiversity) the better an ecosystem can sustain itself

When biodiversity increases

• Sustainability decreases

• Sustainability remains the same

• Sustainability also increases

• Sustainability becomes greater by 2

The greater a habitat’s biodiversity, the greater will be that habitat’s

• sustainability over time

• consumption of energy in the form of sunlight

• temperature ranges across the seasons

• distance to the nearest water source.

Anastayjia visited 3 different ecosystems to collect specimens. She visited a grassy area in a tundra and woody area in a Temperate deciduous forest. She collected 20 different types of species from the tundra and 98 different types of species from the forest. Which ecosystem is the MOST sustainable?

• Tundra

• Desert

• Temperate deciduous forest

• Rainforest
