B7 - Ecology
Key terms
Population
all the inhabitants of a particular town, area, or country
Community
a group of interdependent organisms of different species growing or living together in a specified habitat
-
-
Biotic
relating to, or resulting from living things
Limiting Factor
a factor that controls a population's growth, such as organism growth or species population, size, or distribution
-
Producer
organism that makes its own food (autotroph) and produces organic molecules that serve as food for other organisms in its ecosystem
Key terms
Consumer
organism that relies on other organisms for its energy and food supply; also called a heterotroph
-
-
-
Decomposer
an organism, esp. a soil bacterium, fungus, or invertebrate, that decomposes organic material
-
-
Competition
interaction between organisms, populations, or species, in which birth, growth and death depend on gaining a share of a limited environmental resource.
Adaptations
-
-
-
Structural example - Penguins have a short stiff tail. They can lean backwards and balance on their heels and their tail. This reduces heat loss from their feet to the ground.
The colour of a penguin’s body helps to camouflage it when it is swimming. From above, its dark back blends in against the sea and from below, its light front blends in against the sky.
Behavioural example - Adult male penguins huddle together during winter. This helps them to avoid heat loss and survive until spring.
Functional example - A penguin’s resting heart rate can slow down greatly during a dive so that it can conserve oxygen underwater and spend more time finding food.
Key terms
Global Warming
an increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes)
Greenhouse Effect
process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space
Carbon Cycle
the circulation and re-utilization of carbon atoms especially via the process of photosynthesis and respiration.

Extremophiles
An extremophile is an organism that thrives in extreme environments. Extremophiles are organisms that live in "extreme environments," under high pressure and temperature.
Examples ...
Thermophiles are heat-loving and are found in environments like deep sea vents, volcanic soil, and around geysers. Psychrophiles, also known as cryophiles, are just the opposite.
