Year 7 Ecology
The study of the relationships of organisms with one another and their environment.
Non-living factors that affect the living of organisms (sand, water, etc.)
Living factors that affect the living of organisms (animals, plants, etc.)
Two or more organisms of the same species
Multiple populations that interact in an area
The interactions between abiotic things and the biotic community in an area
A characteristic that is inherited by an organism that helps it to thrive in its environment
The location where an organism lives
Ultimate source of energy for all living things.
A group of living organisms consisting of similar individuals capable of reproduction and give fertile offspring.
A series of steps in which organisms transfer energy by eating and being eaten
What is going through a food chain, starting with the sun and then passing from one organism to another?
When organisms of two different species live closely together in a relationship that lasts over time.
Relationship in which one partner benefits and the other is harmed
Relationship in which one organism (predator) attacks another (prey) for survival
Relationship in which each partner benefits from the relationship
Relationship in which one partner benefits and the other is not affected.
Relationship where both organisms struggle for the same resources
Pyramid of Numbers
Illustrates the number of organisms at each level of the food chain. The number of organisms decreases as the pyramid levels increase.
The network of all the interconnected food chains in a community
An organism that gets its energy by making its own food from light or chemical energy
An organism that gets its energy from eating other organisms for food
Organisms that eat the food made by producers. Can be herbivores, carnivores or omnivores
The process in which the cells of organisms use oxygen to get ENERGY from food. giving CO2 and Water as by-products.
The process in which plants (producers) make their own food from sunlight using CO2 and Water.
An organism, usually a bacterium or fungus, that breaks down dead plants and animals into simpler substances.
They are green plants that make their own food by photosynthesis.
Oorganism that obtain energy and nutrients by feeding on other organisms.
Consumers that obtain their energy by eating plants only.
Consumers that obtain their energy by eating animals only.
Consumers that obtain their energy by eating both plants and animals.
