List 1 abiotic factor and 1 biotic factor that could effect an ecosystem.
Abiotic - water, sunlight, wind, rocks, mountains
Biotic - plants, animals, microorganisms, bacteria
Which type organism in a food web gets energy from the sun?
Producers
Provide an example of an organism whose migration patterns are affected by climate change
Monarch butterflies, caribou
Provide 1 example of an invasive species
Asian carp, zebra mussels, purple loosestrife
In which type of relationship do both organisms benefit?
Mutualism
What types of animals are found in a desert ecosystem?
Lizards, snakes, camels
An organism that has no natural predators
Apex or Top predator
Provide 2 examples of things humans do that negatively imact the biosphere
Pollution, deforestation
Name 2 examples of endangered species
Amur leopard, polar bear, Afrian elephant, sea turtle, panda, 3 toed sloth,
What is the difference between a predator and a prey
Predators are hunters and kill and/ or eat other organisms, while prey are the organisms that are hunted and killed
What type of ecosystem is a swamp?
Wetland
What is the name for organisms that only eat producers?
Herbivores
What is the Greenbelt?
A large protected area of forests, wetlands and farmland in Ontario
Name 1 way that invasive species could move into a new area
Ballast water, hiking and camping equipment, accidental release, travelling on ships and planes, etc.
Barnacles eat bacteria off of whales, but the whales don't even notice they are there. What type of relationship is this?
Commensalism
What is the difference between a community and a population?
A population only includes organisms of the same species, while a community includes all living things in a given area
What is the difference between a food chain and a food web?
A food chain shows the simply path of energy flow, while a food web shows several food chains interconnected.
Name 2 things you can do to protect the biosphere
Less pollution, plant trees, conserve electricity and water
What are the 3 levels of risk that endangered species can be categorized as?
Name 1 organism that humans have a mutalistic relationship with and explain why
Pets - we take care of them and they bring us joy
Cows - we give them food and they give us milk
Plants - we breahte out CO2 that plants need, and they release oxygen that animals need to breathe
Name one ecosystem that is common in southern Ontario
Temperate forests, grasslands
What would happen to a tertiary consumer if secondary consumers went extinct?
There population would decrease and may even go extinct because they are losing a food source.
Describe 1 positive impact of the Greenbelt
Stops urban sprawl which protects natural habitats, helps clean the air and water
Why are invasive species harmful?
They outcompete native species for resources and have no natural predators, so their population grows rapidly
Provide an example of parasitism
Mosquitoes feed on human blood/ fleas feed on animal blood and cause diseases and skin irritation
