Science Gr 5 Ecosystem

Biotic : are living things like plant and animals

Abiotic : are non-living things like soil, sunlight, air, and water

Ecosystem : are all living (biotic) and non-living (abiotic) things in an environment

Population : all members of a single species in an area at a given time

Community : is made from many different populations including all the living things in an ecosystem

ecosytem

population

community

 

food chains : model the feeding relationships between organisms in an ecosystem and the energy in food chain starts with the sun

Producers : are organisms the use the sun's energy to make sugar and oxygen and they are the base of every food chain 

Consumers : is any animal that eats plants or other animals

Herbivores : animals that eat producers ( plants ) like squirrels, some birds, some insects and grazing animals

Carnivores : animals that eat other animals like bobcats and hawks

Omnivores : are animals that eat both plants and other animals like raccoons, mice and some crabs

Decomposers : are organisms that obtain energy by consuming wastes and dead organisms like fungi, bacteria, termites and many worms' species 

Scavenger : is a consumer that cats the remains of dead animals that it didn't hunt or kill like vultures, raccoons, jackals, crows and some crabs 

Food web : is a network of food chains that has some links in common. Predator: is a living thing that hunts and kills other living things for food

 Prey : are organisms that are eaten by predators

 Energy pyramid : is a diagram that shows the amount of energy available at each level of an ecosystem

 

Ecosystem

--is passed on from one organism to another............. In a food chain

Waste

 Sunlight

 Energy

Gas

What is a consumer

An animal that does not make its own food

an animal that eats other animals

a living organism that uses sunlight t make its own food

an animal that has no known predators

 

Producers are ------- ---- because they get energy from the sun, make their own food, and make food for some animals

not an important part of the food chain

animals such as deer and zebras

 the first part of the food chain

 break nutrients down into the soil

 

What is a food chain

 model the feeding relationships between organisms in an ecosystem

An animal that eats other animals

A living organism that is able to use sunlight to make its own food

An animal that has no known predators

 

Producers are ---------because they get energy from the sun, make their own food, and make food for some animals

not an important part of the food chain

animals such as deer and zebras

What is a producer

An animal that eats other animals

  A living organism that uses sunlight to make its own food

An animal that only cats plants An animal that has no known predators

 

A carnivore is an animal that only eats meat

True

 False

 

food chain is a series of relationships between members of an ecosystem so that ----------------can be transferred between them

food

sunlight

 energy

 water

An example of a food chain in a pond environment would be : algae : water bug : fish : otter. In this example the is at the bottom of the food chain

 algae

water bug

 fish

otter

the flow of energy in an ecosystem

 Grass - cow - human

 Caterpillar - leaf - human

  Cow - grass
