Flashcards in B7- Ecology Deck (23):
What is a habitat?
The place where an organism lives.
Define a population.
All the organisms in one species, living in a habitat.
What is a community?
All the populations of different species in a habitat.
What is an environment?
The conditions surrounding an organism.
Define an ecosystem.
The interaction of a community of living organisms with the abiotic parts of their environment.
What 6 resources do plants compete for?
-mineral ions from the soil
What 4 resources do animals compete for?
What is interdependence?
Species in a community depending on other species for things such as food, shelter, pollination and seed dispersal.
What is the term for species in a community depending on other species for things such as food, shelter, pollination and seed dispersal?
What can interdependence mean when there is a change in an ecosystem?
It can have far-reaching effects.`
What are the 5 kingdoms of organisms?
What is are abiotic factors?
Non-living factors which affect organisms.
What are biotic factors?
Living factors which affect organisms.
Name 7 abiotic factors.
-Wind intensity and direction
-Soil pH and mineral content
-Carbon dioxide levels (plants)
-Oxygen level (aquatic organisms)
Name 4 biotic factors.
-Availability of food
What is a stable community?
One where the populations don't fluctuate very much; they are in balance.
What are the three types of adaptation?
-Functional (internal chemical reactions)
How are camels adapted to live in hot conditions?
-Thin layer of fat
-Humps of fat that can be broken down into water
-Large surface area to volume ratio
How are animals that live in cold conditions adapted to their environment?
-Thick layer of blubber for insulation
-Low surface area to volume ratio
How are arctic animals adapted to their environment?
-White fur to camouflage against the snow
-Helps them sneak up on prey/hide from prey
Give an example of a behavioral adaptation.
Swallows moving to warmer climates during the winter.
Some microorganisms are adapted to live in very extreme conditions. What are these called?
