Biomagnification, Biological Controls and Succession

The ecosystem which remains stable for long periods of time, usually includes many dominant species, like large trees is called

• Pioneer Species

• Climax Community

• Succession

• Evolution

Answer explanation

Dominant species like large oak trees, pine trees are in climax communities.

What are (non-native species)- not originally living in a specific area that start succession

• Pioneer species

• Climax Community

• Evolution

• Biosphere

Answer explanation

Lichen and mosses are common pioneer speices

Natural predators that eat insects or plant species that are harmful to humans or their environment are called

• Succession

• Biological Control

• Insecticide

• Pesticide

Answer explanation

Bats are good examples of biological controls for insects

Chemicals that are used to kill insects that are harmful to plants, like agricultural crops.

• Biological Control

• Pesticides

• Roundup

• Herbicides

Answer explanation

Using Biological Controls can reduce the use of harmful chemicals like pesticides.

The increase in a concentration of a pollutant, like DDT or mercury, as it passes through the food chain.

• Pesticides

• Biosphere

• Food Chain

• Biomagnification

Answer explanation

Lesser concentration at the bottom of a pyramid and higher concentration at the top.

ROCKS→MOSS→GRASSES→ SHRUBS→TREES describes

• Biomagnification

• Ecological Succession

• Evolution

• Biosphere

Answer explanation

Ecological succession in a pond: POND →PLANTS AND ORGANISMS START TO DIE→SEDIMENT BUILDS UP→POND GETS SHALLOW→ GETS SWAMPY→ FIELD

A measurement of the degree to which species vary within an ecosystem.

• Biomimicry

• Biodiveristy

• Regularity

• Succession

Answer explanation

As biodiversity increases, STABILITY of an ecosystem increases

All of the following are how man has affected biodiversity in some areas except...

• CUT DOWN TREES (FOR WOOD)

• PLANTED ALL OF THE SAME CROP IN AN AREA

• KILLED ORGANISMS AND DESTROYED THE FOOD WEB (BECAUSE ALL ORGANISMS ARE LINKED TO ONE ANOTHER IN ONE WAY OR ANOTHER)

• REMOVED VEGETATION FOR HOUSES, PARKING LOTS, ETC.

• Creating protected areas like bird sanctuaries
