Ecosystem Effects on the Environment

Prey

• that is eaten by another animal

• a type of predator

• an animal that hunts for food

• a plant that consumes insects

Interdependent

• depending on each other in an ecosystem

• living independently without any interaction

• competing for resources in an ecosystem

• having no effect on one another

Resources

• an organism needs to survive and grow (e.g., oxygen, food, water)

• a type of energy source for machines

• a collection of tools for construction

• a method of communication between species

Food Chain

• A sequence of energy transfer in an ecosystem

• what eats what in a habitat

• A list of all the animals in a habitat

• The process of photosynthesis in plants

Population

• of individuals of a specific organism

• of all organisms in a given area

• of different species living together

• of organisms that can interbreed

Food Web vs. Food Chain

• A food web is a single path of energy flow.

• A food chain is many food chains linked together.

• A food web is many food chains linked; a food chain is a single path.

• A food chain represents all organisms in an ecosystem.

Food Web

• a network of food chains in an ecosystem joined together

• a single food chain in isolation

• a diagram showing only producers

• a list of all animals in an ecosystem

Competition

• fighting for the same resources

• working together for a common goal

• sharing resources equally

• ignoring each other's presence

Grass → hare → lynx

• of a food chain

• of a food web

• of a habitat

• of a symbiotic relationship

Predator

• that eats another animal

• that lives in water

• that is a herbivore

• that hunts during the day
