Which of the following is true about all autotrophs?

• They perform photosynthesis to obtain nutrients.

• They only perform cellular respiration to obtain nutrients.

• They consume other organisms to obtain nutrients.

What process is today's lesson about?

• carrying capacity

• ecological succession

• food chains

What process does the following image show?

• ecological succession

• photosynthesis

• heterotrophic nutrition

• carrying capacity

Ecological succession refers to

• the process of gradual change and recovery in an ecological community over time after a disturbance

• the process of rapid change and recovery in an ecological community over time after no disturbance

• the process of gradual change and recovery in an ecological community over time after no disturbance

• the process of rapid change and recovery in an ecological community over time after a disturbance

Select some examples that can cause disturbance in a ecosystem.

• a fire that destroys most/all of the species in an area

• a group of humans that remove all the plants in an area to make a parking lot or a farm

• students planting new trees in an area

• a tsunami (giant wave) that destroys all the habitats of a species in an area

A pioneer species is

• the first species to return after a disturbance because it requires limited resources

• the most biodiverse and most stable stage

Why is Stage B (Shrub Stage) important for the next stage, Stage C (Pine Forest Stage)?

• each stage prepares/modifies the ecosystem for the next stage

• each stage dies off to make space for the next stage

• each stage decreases in biodiversity

A climax community is

• the first species to return after a disturbance because it requires limited resources

• the most biodiverse and most stable stage

After a volcanic eruption, lava covers the land. What is the order that plants grow to repopulate the area?

• Lichens → Shrubs → Grasses → Trees

• Lichens → tree → shrubs→Grasses

• Lichens → Grasses → Shrubs → Trees
