Total questions: 11
Worksheet time: 6mins
A process of gradual, natural change and replacement of populations of an ecosystem over time is known as:
biodiversity
adaptations
ecology
succession
The first species to live in an area that has no ecosystem is known as a:
pioneer species
climax species
consumer
primary species
The main difference in primary and secondary succession is that:
primary succession starts after a natural catastrophe such as fire
secondary succession occurs without soil
producers are the first organisms in primary succession but not secondary
primary succession begins without soil
Communities of organisms that have stopped changing much and which have stable populations of organisms are known as:
climax communities
stable communities
pioneer communities
symbiotic communities
After a volcano erupts, the lava cools into rock. Over many years, living things begin to populate the area in a process known as:
evolution
biodiversity
primary succession
secondary succession
An example of a pioneer species would be:
black ant
lichen
pine tree
hickory
A type of succession that begins with weeds and small grasses is:
primary succession
secondary succession
climax succession
producer-based succession
Succession that ends with a climax community:
primary
secondary
both primary and secondary
neither primary nor secondary
Primary succession differs from secondary in that:
Primary succession takes much less time to occur
Secondary succession takes 1000s of years
Secondary succession happens when there is no soil present
Secondary succession takes 100s of years
An example of a climax plant community would be:
lichens, mosses, ferns
oaks, hickory, chesnut
grasses, shrubs
lichens, mosses, willows
Organisms that appear at II in this succession picture are known as:
pioneer species
climax species
bacteria
primary consumers
