Ecological Succession

Master ecological succession! This worksheet covers primary vs. secondary succession, pioneer species, and biomes.

Ecological Succession What type of succession is shown in the picture below: Primary or Secondary? Click on the blue circle and type in your answer-first species or pioneer species-mature and no more succession (oak with bare rock Primary starts with bare rock first species or pioneer species -mature and no more succession (oak What type of succession is shown in the picture below: primary or secondary? Click on the blue circle and type in your answerWord Bank-begins after a disturbance-pioneer species other than lichens-takes a shorter period of time to reach Secondary begins after a disturbance pioneer species other than lichens takes a shorter period of time to reach How do Primary and Secondary Succession differ? Primary vs. Secondary Sort the descriptions into Primary and Secondary Succession (if you accidentally put it on the wrong side- you can change it!) Primary Succession Glacier melts revealing bare rock Lichen and Moss break up rock Takes 1000s of years Soil must be created over time Lava creates new rock Pioneer species: Lichens Secondary Succession Abandoned farm Flash flood sweeps through desert Pioneer species: Grasses Soil is already present Takes 100s of years Fire sweeps through forest Match the order! Place the images and descriptions in order by matching the correct number in the sequence of Primary Succession.Click the orange circle and drag it to another orange circle on the opposite side. 1. 2. 3. 4. 5. 6.

A digram that shows how much energy is available at each feeding level in an ecosystem is a(n) food web food chain water cycle energy pyramid Little precipitation and extreme temperatures are main characteristics of which biome? desert boreal forest grassland deciduous forest Where would you expect to find a greater variety of organisms- in a biome or in a microhabitat? Explain. Compare and ContrastChoose two biomes. Describe how the different environments support different varieties of organisms. The most effective way to preserve biodiversity is through captive breeding habitat destruction habitat preservation habitat fragmentation The series of predictable changes that occur in a community over time is called natural selection adaptations ecology succession What types of natural disturbances can cause secondary succession to begin? Fill in the blanks. Pioneer species are the first species to populate an area.Extinction occurs when all members of a species disappear from Earth.Lichens and mosses have began to grow, this allows for soil creation to occur, allowing more organisms to grow. This type of occurrence is called primary succession.Many organisms come back after an extreme disturbancehappens. This secondary succession occurs faster because soil is already in existence in the area.
