Слайд 2Community is a group of interacting species living in the same location.
Ecological succession is the process by which ecosystems change and develop over time. During succession plants, animals and other organism species are replaced with different species.
Слайд 3Types of ecological succession
Primary succession occurs in areas where no living organisms
lived before.
Primary succession would take place on new volcanic islands (вулканикалық аралдар/вулканические острова), bare rocks (жартас жыныстары /голые скалы) and other places.
Слайд 4Types of ecological succession
Secondary succession occurs on ready soil or a place
where other living organisms lived before.
Secondary succession occurs after fires, floods (су тасқыны/ наводнение), drought (құрғақшылық/ засуха), and some human activities.
Слайд 5Fact
Fire gives life too. Jack pine is a plant which grows in
Northern America. Its cones only open and spread seeds after forest fires.
