What is an ecological niche?
It is the role a species plays in its habitat, including -what it eats -where it lives - how it survives.
What does an ecological niche include for a species?
“1.Living environment (its Habitat) • Diet • Activity cycle”
What is a habitat?
It is the environment where a species lives, finds food and water, and survives EVERYTHING YOU NEED TO SURVIVE
What are the main ways living organisms can adapt to their environment? Name all the major types of adaptations.
• MOVE: Adaptations in movement Example: swimming bodies, gliding wings, slithering, jumping, climbing. • EAT: Adaptations related to diet Example: bird beak shapes, types of teeth in mammals, carnivorous plants. • REPRODUCE: Adaptations for reproduction Example: flower shapes, scents, colours attracting specific pollinators. • CLIMATE: Adaptations to climate Example: thick fur in Arctic animals, changing fur colour with the seasons. • COMMUNICATE: Adaptations in communication Example: colours, gestures, sounds, scents/light used to warn, attract, or signal.
Give an example of “Move” adaptation
Duck feet
Give an example of “Eat” adaptation
-bird beak shapes - types of teeth in mammals
Give an example of “Reproduce” adaptation
• Flowers • Spores
Give an example of “Climate” adaptation
-Artic fox ears, tail, -Arctic animal change the colour of its fur with the seasons
Give an example of “Communication” Adaptation
• Deer tail -Beaver tail
What is a producer, and how does it obtain its energy?
It a plant that makes its own energy through photosynthesis using sunlight. At the base of every food chain
What is the role of a producer?
create energy rich food that supports all other living organisms.
Define a consumer
Organism that cannot make its own food so it must eat other organism to get energy.
What do primary consumers eat?
Primary consumers eat producers (plants). They are herbivores
What is a secondary consumer?
They feed almost exclusively on primary consumers. They are carnivores ex: frog, fox
What is a tertiary consumer?
“They feed almost exclusively on secondary consumers. They are carnivores. ex: Wolf, Owl”
What are Omnivores?
They feed on producers and on primary, secondary and tertiary consumers. ex: human, black bear
What do you call an animal that feeds on the bodies of already dead animals (bodies of consumers)?
Scavenger
Define decomposers
They are recycling Pros. -recycle plants and dead animals into nutrients that return to the soil. ex: worms
What is a food chain?
Flow of energy and nutrients pass from one living organism to another in an ecosystem.
In a food chain, what is the direction of the arrows showing?
the direction of energy flow from one organism to the next.
What is a food web?
Series of food chains, often interconnected to make an ecosystem
What is an ecosystem?
a system made up of living things (plants, animals, organisms) and non-living things (air, water, soil) interacting together in a specific environment.
What is a population made up of in an ecosystem?
-All the individuals of the Same species -That share the Same habitat -At the Same time.”
What forms the middle ground between terrestrial and aquatic environments?
Wetlands
