Ecosystems
What is the main difference between terrestrial and aquatic ecosystems?
Terrestrial is on land and aquatic is in water.
What is the role of the decomposer?
Breaks down decayed material to give nutrients to the soil.
What is the difference between an herbivore, carnivore, and omnivore?
Herbivore - eats plants, Carnivore - Eats meat, Omnivore - eats both plants and meat
What is the order of a basic food chain?
Sun, producer, consumer, decomposer
Give two examples of aquatic ecosystem.
River, lake, pond, ocean, swamp. bog, marsh, salt marsh, etc.
What are some examples of producers?
Plants like grass, flowers, leaves, etc.
True of False
Herbivores produce their own food.
False!
Herbivores consume plants!
What is a food chain?
The transfer of energy between organisms.
Give two examples of terrestrial ecosystems.
Grasslands, desert, forest, rainforest
Where does every producers get their energy from?
Sunlight
Name a consumer that is a carnivore (only eats meat).
Wolf, tiger, some sharks, etc.
What is the primary (beginning) source of energy on every food chain?
The Sun
Name 3 nonliving things needed for there to be life in an ecosystem.
Soil, sunlight, water, air, nutrients
What are some examples of consumers?
Animals like Rabbit, Grasshopper, Wolf, Humans, etc.
What is an example of an example of a consumer that is an herbivore (only eats plants)?
Rabbit, grasshopper, zebra, cow, some fish, etc.
What do the arrows represent in a food chain?
The arrows show flow of energy between organisms. They point to where the energy goes.
Describe a rainforest ecosystem.
Located near the equator, very hot and wet all the time, huge variety of plants and animals
Explain the difference between producer, consumer, and decomposer.
A producer creates their own food (energy). A consumer gets their energy from eating others. A decomposer breaks down dead things to put nutrients back in the soil.
What is an example of a. consumer that is an omnivore (something that eat plants and animals)?
Humans, fox, bears, etc.
What would happen is something was removed from a food chain?
Example: All the trees in a forest were destroyed in a fire.
The population of consumers who needed those trees would decrease.
The balance of life would be no longer be there.
