Ecology Flashcards
Ecology
The study of plants and animals in their environment and the relationship between them.
Enviroment
The environment is everything that surrounds an animal or plant (example is air, water, rocks and soil)
Habitat
The area where the place a plant and animal lives
Types of habitats
Each habitat has its own community of organisms
For example hedgehogs, snails, foxes, and primroses belong to the Woodland habitat
Interdependance
This is how organisms depend on each other for their survival. example: Buttercups depends on bees because bees pollinate.
Animals depend on other animals
Foxes need rabbits for food
Rabbits need grass for food
Plants depends on other plants
Ivy needs large trees to grow up to get light
Ecosystem
All the plants and animals in an area interacting with each other and their enviroment
bigger than a habitat
Feeding habits
Producer - Plants that make their own food e.g. grass, dandelion, nettles
Consumer - Animals that get their food by eating plants or other animals
Herbivore - An animal that eats plants e.g. rabbit, sheep, slug, snail
Carnivore - an animal that eats other animals e.g. fox, hawk, ladybird
Food chain
A food chain snows how one organism eats another and so on
Food chains must start with green plants because they are the only things that can make food
Feeding levels
The position of an organism in the food chain is called its feeding level.
the first feeding level is always a green plant
Energy transfer in the food chain
The energy in any food chain comes from the sun
Plants have the most energy as they make it from the sun
Each step loses more and more energy
A food web
Single food chains are rare, most are inter connected
More than one organism eats the same food source
Competition
Competition occurs when two or more organisms seek a resource that is limited
Plants compete for light, water, minerals, and space
animals compete for food, shelter, territory and mates
Adaptations
Adaptations are features that give an organism a better chance of surviving in their habitat
