Biodiversity is the ____________ and variability of __________ on earth

• variety

• life

• diversity

• difference

Which term best describes the number and variety of organisms in a given area during a specific period of time?

• limiting factor

• biodiversity

• succession

• sustainability

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

What is one way that a temperate rainforest is different from a temperate deciduous forest?

• A temperate rainforest has large populations of grasses rather than tall trees.

• A temperate rainforest is made up of palm trees rather than coniferous trees.

• A temperate rainforest has a long rainy season rather than moderate, year-round rainfall.

• A temperate rain forest has trees that lose their leaves in winter rather than keeping them year-round.

Students were asked to make a claim supported with evidence to answer the question, "Which ecosystem would be most sustainable if all the grasses died from severe drought?" What claim is valid and supported by the evidence?

• A. The forest ecosystem is most suitable because there are more top predators.

• B. The grassland ecosystem is most sustainable because there are fewer organisms that eat grass.

• C. The forest ecosystem is most sustainable because most of the animals can eat other organisms.

• D. The grassland ecosystem is most sustainable because there is less competition for food.

What is biodiversity?

• The interaction of biotic and abiotic factors in an ecosystem

• The number of different living things in an ecosystem

• The age of an ecosystem

• The type of climate an ecosystem has

A pioneer species such as __________ are a combination of algae and fungus that grow on bare rock.

• A. Mistletoe

• B. Legumes

• C. Lichens

• D. Mushrooms

Refer to the food web. If the grasses in each ecosystem are attacked and killed by a disease, which ecosystem will most likely survive?

• A. The prairie ecosystem, because few organisms eat grass.

• B. The tundra ecosystem, because there is a variety of producers.

• C. The prairie ecosystem, because there a fewer top predators.

• D. The tundra ecosystem, because it has more herbivores.

How are tropical plants such as bromeliads adapted to the biome in which they live?

• They grow from tree branches rather than the forest floor, which helps them to absorb more sunlight.

• They have long, thick roots, which helps them to gather the nutrients that are found deep within the soil.

• They have hollow leaves and stems for storing water, which helps them to survive long periods with little rainfall.

• They lose their leaves during the winter, which helps them to save energy when the temperature falls and prevents the buildup of snow.

Which is more sustainable, a food web or a food chain?

• A food web

• A food chain
