Describe how glaciers affect the earth's air temperature

glaciers reflect the light to cool down the earth

100

What stage of logistic growth is the human population currently in?

exponential growth

100

What is the difference between an autotroph and a hetrotroph?

autotrophs make energy from nonliving sources, heterotrophs make energy from living things
100

what is the climate like in the tundra biome?

extremely cold, not much vegetation

100

how does the greenhouse effect affect glaciers? How does this affect temperature

it causes glaciers to melt which causes the temperatures to rise.
200

What is the greenhouse effect?

molecules of greenhouse gases trap the sun's heat on earth heating up the planet

200

What is the difference immigration and emigration?

immigration is organisms moving into an area, emigration is organisms leaving an area

200

What are the two ways autotrophs make energy?

photosynthesis, chemosynthesis

200

Name 3 animals that live in the savannah.

lions, zebras, buffalo

200

How does deforestation affect the rainforest ecosystem?

destroying habitats of animals

300

Describe how the population of rabbits might be affected by limited food over the next generations

population would decrease then increase over and over again

300
What is a limiting factor?

something that stops a population from growing

300

What is the difference between a food chain and food web?

Food web is multiple food chains put together.

300

What is an adaptation animals have in the desert?

Ability to camouflage and retain water.

300

How does overfishing affect the ocean ecosystem?

when fish die, no animals have things to eat

400

what happens to an ecosystem when a species has no limiting factors?

they take over the ecosystem and their population grows forever

400

What is the difference between a density-dependent and density-independent limiting factor?

Density-dependent depends on the population size, density-independent does not depend on the population size

400

Describe the difference between abiotic and biotic factors

abiotic are nonliving, biotic are living

400

Name one example of how plants adapt to survive.

thorns, long roots

400

How do carbon emissions cause global warming

heat is trapped by the carbon molecules heating the earth

500

List 3 limiting factors for humans

food, water, space, disease, natural disasters,

500

Describe the three phases of logistic growth.

exponential growth, growth slows, growth stops

500

Describe how energy moves through a food chain and what biotic and abiotic factors are included

sun, autotroph, heterotroph

500

What are the key differences between each biome?

Temperature, water, sunlight

500

Why is global warming a difficult issue to solve?

we have not found alternatives to sustain daily life yet and a lot of people do not care
