1. What is best to sustain an ecosystem?
a large variety of living things (bio diversity)
if a large amount of trees were cut down in a forest, the remaining plants in the ecosystem would need to develop traits that help them do what?
withstand direct sunlight
t/f The series of events by which life starts coming back after a volcano has erupted would be an example of secondary succession.
false
How does biodiversity contribute to the sustainability of an ecosystem?
...
A Micro organisms is an example of?
Biotic factor
An example of a typical pioneer species, that is one that appears in the earliest stages of ecological succession, is
weeds
Plants with deep roots are able to reach cooler regions and reach deeper water. This is important for plants in what climate?
hot and dry
Some students take care of a vegetable garden. The students leave part of the garden empty and bare with no soil or plants. Which of these will most likely occur first?
growth of weeds
coldest biome?
tundra
space under a rock is an example of?
Micro Habitat
Primary succession takes place in an area where
no soil
The desert receives little or no rainfall, leaving little for organisms to drink. Organisms that live here most likely-
store large amounts of water internally
What would not contribute to the biodiversity in an area
Wind
which biome has the greatest biodiversity?
Tropical rainforest
newly formed islands are an example of what?
Primary Succession
t/f It can take hundreds of years for a disturbed forest to develop into a climax community.
true
t/f Ecological succession usually includes changes in the number of overall plants, the size of dominant plants, and the number of plants of any one species.
true
Sand dunes erode and sea water begins to move into a forest. Forest plants will probably develop this trait-
Ability to tolerate salt
a pine cone that releases seeds during and after a forest fire is an example of?
pioneer species
This Biome has a climate dependent on location and seasons
Marine Biome
he habitat with the greatest sustainability will be the one that
Ecological succession takes place in an area where?
Changes in the community species composition occurs over time
Humans can protect the sustainability of the rainforest by
leaving the rainforest alone so the biodiversity remains.
a group of rabbits is an example of?
population
This Biome has the high biodiversity with as many as 100 different tree species
Rainforest
