Relationships
What are the 3 types of symbiosis?
What is PARASITISM, COMMENSALISM, and MUTUALISM
The living things in an ecosystem
What is BIOTIC
Organisms that can produce their own food
What is PRODUCERS
A plant or animal that has migrated to a place where they are not native
What is INVASIVE SPECIES
Where is the world is there the most biodiversity?
Near the equator.
A wasp lays its eggs on the back of a caterpillar. When the wasp eggs hatch, the larva will eat the caterpillar and kill it.
What is PARASITISM
The non-living things in an ecosystem
What is ABIOTIC
The place where an organism lives
What is HABITAT
The gradual growth of organisms in an area that was previously bare, like newly exposed or formed rock.
What is PRIMARY SUCCESSION
What are 4 basic needs of animals?
What is FOOD, WATER, AIR, SHELTER, SPACE
Bees eat pollen from flowering plants and receive food. As bees fly from plant to plant they help the flowering plant pollinate and reproduce.
What is MUTUALISM
A model that shows how the energy stored in food is passed from one organism to another.
What is FOOD CHAIN or FOOD WEB
Variations that help an organism survive
What are ADAPTATIONS
What is extirpation?
The extinction of a species in certain locations.
Emperor penguins huddle together in large groups to stay warm during the freezing Antarctic winter. Is this an example of a structural or behavioural adaptation?
Barnacles often attach themselves to the shells of sea turtles. The barnacles benefit by gaining a safe place to live and access to food particles as the turtle swims through the water. Turtle is not harmed.
What is COMMENSALISM
Where is the most energy found in a food chain (or pyramid of numbers)?
What is THE PRODUCERS
The variation of life on earth
What is BIODIVERSITY
The role or position that an individual has in its community, and its interaction with the environment.
What is NICHE
In a population of Arctic foxes, some individuals have a thicker fur coat than others, allowing them to survive colder winters better. Is this an example of variation or adaptation?
What is VARIATION (Difference within a species)
As the toxins move up the food chain, their concentrations become higher in each organism.
What is BIOMAGNIFICATION
What are the two main types of ecosystems?
What is TERRESTRIAL (land) and AQUATIC (water)
Another way that we classify the levels in the food chain (groups of organisms that belong to a category on the food chain)
What is TROPHIC LEVELS
Consumers that don’t usually kill for their own food. Instead, they feed off the remains of living things that are killed by other consumers
What is SCAVENGERS
The impact of a person or community on the environment, expressed as the amount of land required to sustain their use of natural resources.
What is ECOLOGICAL FOOTPRINT
