This is the word for a species that has completely died out; no organisms of that species remains alive

extinct

Which is the largest saltwater ecosystem?

open ocean

Biodiversity is a combination of the words ____________________________ and __________________________.
biological, diversity
200

Which two biomes receive the least amount of yearly rainfall (less than 25 cm)?

Tundra and Desert

200

This biome has the best soil on Earth.

grasslands (temperate grasslands/prairie or tropical grasslands- savanna)

200

This is a where fresh water from rivers mixes with salt water from the ocean, creating brackish water. 

estuary

200

Mangrove trees have this adaptation to help them survive

they developed prop roots (roots that stick up out of the ground)

200
Define biodiversity.
Biodiversity is the great abundance of different life forms; millions of species that can live in Earth's many ecosystems
300

The temperature of a biome closely depends on its geographical distance from the __________________________.

equator

300

Which kind of forest contains mainly maples, oak, ash, and birch trees?

deciduous forest

300
Name the two main kinds of water ecosystems.
freshwater and saltwater
300

This forest contains mainly maples, oak, ash, and birch trees which do this to survive in the winter

leaves change color then fall off of the trees

300
What are the three major factors that determine the biodiversity within an ecosystem?
size, terrain, latitude (distance from the equator)
400
Ecosystems that cover large areas of land are called ____________________________.
biomes
400

A structure of calcite skeletons built up by tiny animals in warm, shallow ocean water.

coral reef

400

3%
400

To survive in the desert, what adaptation(s) do plants need?

ways to conserve/store water (waxy cuticle, large shallow root systems, modified leaves/needles)

The greatest threat to biodiversity is _________________ __________________________.
habitat destruction
500

Name the 6 major biomes on earth:

deciduous forest, desert, grasslands (tropical/temperate), taiga, tropical/temperate rain forest, tundra

500

Name three ways in which animals help people.

(answers will vary) ex/ provide us with food, materials for clothing, building materials, medicines, decomposers keep soil fertile for planting, bacteria break down wastes and purify water

500
Name the three types of freshwater ecosystems and the three types of saltwater ecosystems.
freshwater: river, lake, wetland saltwater: shoreline, coastal ocean, open ocean
500

Explain what would happen if there was no plant life on earth.

All humans and animals would become extinct; we cannot live without oxygen, which comes from plants.

500

Name three ways in which humans can save ecosystems and encourage species' survival.

(Answers will vary.) Ex/ -stop deforestation (cutting down trees) -stop hunting -stop pollution
