Review and Practice

Ecosystems

• A group of living things.

• These things interact with one another as well as their environments.

Communities

• Groups of species.

• Living within the same ecosystem.

Habitat

• Place that animals live.

• Has food and shelter.

Producer

• Make their own food from energy of the sunlight.

• Provides food for animals.

Consumers

• Categorized by Primary, Secondary and Tertiary.

• Primary consumers are Herbivores, meaning they only eat plants.

Consumers

• Secondary consumers are Carnivores.

• Carnivores only eat other animals.

Consumers

• Secondary Consumers are also called Omnivores.

• Omnivores eat both plants and animals.

Consumers

• Tertiary consumers are at the top of the food chain.

• Humans are often a good example of Tertiary consumers.

Decomposers

• Consist of fungi and bacteria.

• Break down dead matter and transfer those nutrients back into the soil.

• These nutrients help plants to produce and create more producers.

Energy Pyramid

• Shows the flow of energy at each trophic level in an ecosystem

• The trophic level of an organism is the number of steps it is from the start of the chain.

Where do insects go in the Winter?

• Insects have a variety of ways to try to survive the winter:

• They hibernate,

• They fly south,

• They die hopefully after laying new eggs that will hatch after Winter is over.

What is the coldest place on Earth?

• The coldest place on Earth is the South Pole (Antarctica)

• It's temperature has been measured at a record low of -89.2 degrees Fahrenheit.

Does the North Pole actually have a North Pole?

• The North Pole does not have an actual pole because its location is in the middle of the Arctic Ocean.

• It freezes and melts so the "pole" does not have stable ground to place it on.

Does the North Pole actually have a North Pole?

• The Earth's poles are actually points in which the Earth spins.

• These two points of the Earths axis never change.

• They are located in the Artic Ocean (North Pole) and Antartica (South Pole)

Multiple Choice

Multiple Choice

Communities are …

• The same animals living in different ecosystems.

• Various populations of the same species living in the same ecosystem.

Multiple Choice

Habitats are …

• Places where animals live and have food and shelter.

• Places where animals do not exist.

Multiple Choice

Producers …

• Make their own food from the energy of the sun and provide food for animals.

Multiple Choice

Consumers ...

• Are people who buy good from the grocery store.

• Are categorized by Primary, Secondary and Tertiary types. These include Herbivores, Carnivores, and Omnivores

• air

Multiple Choice

Carnivores eat

• meat

• plants

• water

• air

Multiple Choice

Omnivores eat ...

• plants only

• meat only

• meat and plants

• water and air

Multiple Choice

Tertiary consumers ...

• are at the top of the food chain and consume both meat and plants.

• are weaker than herbivores because they live off of water only.

Multiple Choice

Decomposers

• are made up of fungi and bacteria and help bring nutrients back into the ground.
