Biosphere Unit Test Spring 2024

This biome is characterized by grasses, few trees and rich soil. I am talking about

• Temperate deciduous forest
• Taiga
• Savanna
• Tundra

Biodiversity within a species (genetic diversity) is important because.....

• Greater variation increases the chance that some individuals of that population will be able to survive if their environment changes
• Greater variation ensures that the species will become extinct if the environment changes
• Greater variation results in offspring who are genetically the same

What biome is cold, has poor soil, low biodiversity, and trees with needles.....looks like this?

• Tundra
• Taiga
• Temperate deciduous forest
• Chaparral

If I am referring to a group of organisms which are all the same species and live in a particular area, I am talking about...

• A population
• A community
• An ecosystem
• A biome

What are the 3 main climate zones?

• Polar, tropical, temperate
• Micro- Macro-, Mini-
• Savannah, Taiga, Tundra

When 2 different species exist in a close, permanent relationship, where both species benefit, this is called....

• predation
• mutualism
• synthesis
• parasitism

Why is it warm at the equator?

• The sun's rays hit the equator at a slant, so it gets more of the sun's energy
• It is not warm at the equator
• The sun's rays hit most directly at the equator, so this is the place on earth that gets the most energy

Taiga, tundra, temperate deciduous forest, savannah, desert, chaparral. These are all examples of _________

• Climate
• Biomes
• Regions

A certain plant requires moisture, oxygen, carbon dioxide and light in order to survive. These are known as:

• biotic factors
• abiotic factors
• symbiotic relationships
• carnivore-herbivore relationships

Why aren't polar ice caps considered biomes?

• Because they don't have soil or plants
• Because they have very low biodiversity
• Because they have very high biodiversity
