Biomes and Succession

A habitat that receives little or no precipitation will most likely be suitable for organisms that —

• Hibernate for long periods of time

• Are covered in thick fur to keep warm

• Spend most of the day in the sunlight

• Store large quantities of water internally

In the process of ecological succession, grasses appear before shrubs because grasses—

• loosen the dirt for new trees to take root

• provide food for animals returning to the area

• require plenty of sunlight to make their own food

• can grow rapidly even in areas with shallow soil

An example of a typical pioneer species, that is one that appears in the earliest stages of ecological succession, is —

• oak trees

• Spiders

• Weeds

• Humans

Primary succession takes place in an area where —

• no soil or organisms were previously present

• wildfires removed existing prairie grass species

• large organisms outcompete smaller organisms

• weeds grow in a garden next to vegetables

Which of these types of environments experiences the LEAST change in the total number and type of species over time?

• An ecosystem with only pioneer species

• An ecosystem that is in primary succession

• An ecosystem that is in secondary succession

• An ecosystem with a climax community
