Organisms and Environments

This diagram best illustrates which of the following?

• Catastrophic Events

• Desert Biome

• Ecological Succession

What is the job of the pioneer species in ecological succession?

• To create a catastrophic event

• to colonize and help modify the floor to allow other spices to invade the area.

• Help decorate the forest floor.

If an area of land is to be left alone what is most likely to happen to that area?

• be overgrown with small bushes and trees

• bare rock will form

• catastrophic event will occur

• nothing will grow

If a catastrophic event occurs and destroys all of the living organisms what will occur next?

• the ecosystem will forever be dead

• succession will begin and until a climax community has been reached

• nothing will be able to grow

Which organism is most likely going to be a pioneer species where rock has been formed due to a volcanic eruption?

• Grass

• Flowers

• Lichens

• Trees

Which organism help modify the environment during ecological succession?

• Pioneer organims

• Annual plants

• Slow growing organism such as trees

Which of the following best describes a climax community?

• The community begins to decrease.

• The community continues until an environmental change occurs.

• The community will continue even when a catastrophic even occurs.

Which of the following orders will most likely happen during ecological succession?

• lichens, mosses, grasses, trees

• trees, mosses, lichens, grasses

• grasses, lichens, mosses, trees

• lichens, grasses, mosses, trees

Over a long period of time organism started to invade an area where a volcanic eruption occurred, from lichens mosses, grasses, consumers, and trees. Which of the following represents the pioneer species?

• grasses

• lichens

• consumers

• trees

In a climax community we have deer starting to overpopulate the ecosystem. Which of the following is the most likely outcome if the deer continue to populate?

• Biodiversity and sustainability will decrese

• Biodiversity will increase

• Sustainability will increase

• Biodiversity and sustainability will increase.
