UNIT 5

ECOSYSTEM

IS MADE UP OF LIVING THINGS (FLORA, FAUNA AND OTHER ORGANISMS) AND NON-LIVING THINGS (PHYSICAL ENVIRONMENT: SOIL, WATER, SUNLIGHT, CLIMATE, TEMPERATURA…) WHICH WORK TOGETHER TO

MAKE A BALANCED SYSTEM

Habitat: place where living things grow and live.

GROUP OF ANIMALS WHICH BELONG TO THE SAME SPECIES

Different populations interact with each other

Living and non-living things
