life and living

part of an ecperiment that can change

a process where green plants use light energyto make sugars they need to survive.

oxygen

the eprocess in the cells where glucose os broken down and energy is released

Glucose + oxygen ————> energy + carbon dioxide + water

the study of the interactions between organisms with each other and their abiotic environment

a group of one kind of organism all living at the same place at the same time

a group of different populations that all share the same habitat

a self mantaining community or group of communities together with the biotic and abiotic factors that affect them

all the ecosystems on the earth together.

an ecosystem has no particular size but is a clearly defined space.

there are interactions between different kinds of living organisms and the abiotic environment

they need to adapt to the environment and cope with the changes in it

any organism that can make their own food (photosynthesis)

organisms that rely on other organisms for food primary and secondary consumer

make food produce energy + release oxygen - essential for survival

diagrams that show feeding relationships between living things starts with producer ends with decomposers

series of food chains linked up organism feeds on more than one organism

resources will be destroyed unbalancing in ecosystem organisms start competing with each other for resources strong plant or animal will survive
