water vapor

water in its gas state


the process in which a gas changes into a liquid


any form of water that falls to the Earth

water cycle

the continuous movement of water between Earth's surface and the air. Ex: precipitation, runoff, condensation, evaporation

intertidal zone

the shallowest part of the ocean ecosystem, where the ocean floor is covered and uncovered as the tide goes in and out

the continuous exchange of carbon dioxide and oxygen amoung living things

nitrogen cycle

the continuous trapping of nitrogen gas into compounds in the soil and its return to the air


the mixture of dead plant material that can be used as fertilizer

endangered species

a species that is in danger of becoming extinct

threatened species

a species that is in danger of becoming endangered


the process of one ecosystem changing into a new and different ecosystem

primary succession

the beginning of a community where few, if any, living things exist

secondary succession

the beginning of a new community where an earlier community already existed

pioneer species

the first species living in an otherwise lifeless area

pioneer community

the first community living in a lifeless area

climax community

the final stage of succession in an area, unless a major change happens

An example of a benthos

a barnacle

Why would more organisms live in shallow water because...

there is more oxygen, and also more sunlight

which type of ecosystem has both fresh and salt water?


what's an example of a pioneer community?


Nertic Zone

the ocean zone where coral reefs and kelp forests are located

which type of biome has the greatest diversity of plants and animals?

tropical rain forest

Where does the energy that is needed for the water cycle to take place come from?

the Sun

Why can't trees grow in the tundra?

the cold temperature and frozen ground prevent the growth of trees in the tundra

What does the nitrogen-fixing bacteria in soil turn nitrogen gas into?


What is the main difference between primary and secondary succession?

primary succession begins with bare rock

what is it called when a liquid changes into a gas?


Compared with a temperate forest a grassland has...

a lot less rainfall

why are most animals endangered?

because of habitat loss


a cold and snowy biome with lots of conifers

deciduous forest

a biome with a temperate climate and trees with broad leaves

tropical rainforest

a biome that is hot and humid and the seasons change very little and there are many different kinds of plants and animals


a biome where it is cold and there is little precipitation. A layer of permafrost is on the top layer of the ground in this biome.


a biome with lots of grasses and the animals hide in the grasses. Uneven precipitation and warm summers are characteristic of this biome

Where is the tundra located?

at the top of the world around the North Pole

Large amounts of plant life provide habitats for many species of animals in the _____________________________biome

tropical forest

What are the 4 layers in the tropical forests?

emergent layer, canopy, under story, and forest floor

Nocturnal animals

sleep in the day and hunts at night

Where do animals get water if they never drink the water?

seed and plants

What are the challenges facing animals in the desert?

there is not much water and the weather is hot and dry

Why does the rain that falls in the desert evaporate quickly?

The heat of the hot hot sun turns it into a gas

What are the cool deserts like?

They are hot during the summer, cold during the winter, and sometimes known to get snow.

Biome with extreme heat, dryness & cold nights


What must animals in the desert survive?

They must survive extreme heat, searing sun, and a lack of water.

What are the main kinds of plants in the grassland?


What are some animals that live in the grassland biome?

insects, zebras, elephants, and giraffes

Air Pressure is high when the weather is __________.

chimpanzee, common tree shrew, gorilla

Where is the Tropical Rain Forest located?

a little in the USA, in Africa, and South America

What is the climate like in the Tropical Rain Forest?

the average temperature is 70-85 degrees F. The precipatation is 80-400 inches per year.

About how much of the Earth's animals and plants live in the Tropical Rain Forest?

1/2 of the Earth's plants and animals

What is the climate like in the Tundra?

It is usually covered with a blanket of snow and all of the deiciduous trees have lost their leaves.

What causes the seasons to change in a biome?

The tilt of the Earth on its axis causes the Earth to either be closer or further from the sun. The closer a hemisphere is to the sun the warmer the season is. The further the hemisphere is from the sun, the cooler or colder that hemisphere is.

when in the tundra is water available?

only for a little while in the summer when it has rained and the water cannot soak into the ground because it is frozen

What is happening to the rainforests?

they are disappearing because the trees are being cut down.


layer of permanently frozen ground just below the topsoil

The process of naturally recycling water on Earth I called the
