Ecosystems and Biomes

By JENNIFER RISER

Each individual plant and animal could not exist by itself on planet Earth. All living organisms need millions of other living organisms to survive. How these organisms interact with the sun, soil, water, air and each other in a specific area is called an community.

Ecosystems

​

An ecosystem describes a specific area where the organisms work together as a unit. It could be any size from a tiny pool of water to hundreds of square miles of desert. Each ecosystem is different and each has established a balance over time that is important to every form of life .

​

Ecosystem

Multiple Choice

Each individual plant and could not exist by itself on the planet

• True

• False

Multiple Choice

Everything that surround and affects a living thing is called a/an

• Environment

• Photosynthesis

• Extinction

• Population

Multiple Choice

Each ecosystem is different and each has established a balance over time that is important to every form of life

• True

• False

A biome is a way to describe a large group of similar ecosystems. Biomes ​have similar weather, rainfall, animals and plants. There are a number of biomes on planet earth

​

​Biome:

​

The different types of land major biomes are...

1. desert

2. grasslands

3. savanna

4. tundra

5. tropical rainforest

6. taiga forest​

​

Major Biomes

​

The different types of aquatic biomes are

1. marine

2. freshwater

3. coral reef​

​

Aquatic Biomes

Multiple Select

One of the Earth's largest ecosystems with its climate, soil, plants and animals

• Nutrient

• Organic Matter

• Biome

• Extinction

Multiple Choice

What is NOT a characteristic of a Biome?

• Similar plants

• Similar physical characteristics

• Different weather patterns

• Similar rain fall

Multiple Choice

All the organisms of the same kind that live in an ecosystem

• Biome

• Population

• Consumer

• Preditor

Multiple Choice

There are several Biomes on the planet

• True

• False

Multiple Choice

The major biomes on the planet include

• Desert

• Tundra

• Tropical Rainforest

• All of these

Multiple Select

Aquatic biomes include

(there might be more than one answer)

• marine

• freshwater

• desert

• grassland

The Balance of the Ecosystem

Ecosystems maintain balances so that all the organisms within the ecosystem can survive.

These balances involve

1. food

2. water

3. oxygen

4. nitrogen

5. carbon​

​

The sun provides the energy needed by ecosystems. Plants take this energy and use photosynthesis to create sugar which they can use for energy.

Nutrients in teh soil, the air, and water also play a part in keeping the ecosystem thriving and in balance. ​

​

Multiple Choice

What does the sun do for an ecosystem

• It creates oxygen

• It provides the permanent disappearance of species

• It provides energy

• It freezes the ground

Multiple Choice

Ecosystems maintain balances so that all the organisms within the ecosystem can survive.

These balances involve

• food

• water

• oxygen

• All of these

Multiple Choice

Ecosystems maintain balances so that all the organisms

within the ecosystem can survive.

These balances does NOT involve...

• food

• water

• phosphorus

• carbon
