What is the main difference between primary and secondary ecological succession?
Primary begins WITHOUT soil; Secondary begins WITH soil
Primary is the first state and secondary is the second stage
Primary builds plant community; secondary builds animal community.

Grasses → Lichens → Shrubs → Trees
Lichens → Grasses → Shrubs → Trees
Which would result in primary succession?
volcano destroying habitat leaving only soil and ash
Tornado destroying a crop leaving very little soil
Glacier retreating exposing bare rock
limiting factors

We live in a desert. What type of biodiversity do we have here?
High biodiversity
Low biodiversity
Match the following statements with the correct words.
biodiversity
The variety of life found on Earth.
ecological
This type of diversity refers to the ways that species interact with each other & their environment
Genetic
This type of diversity is the variation in genes within a species.
Surviving
Organisms with a large gene pool have a great chance of ____ than a population w/limited variability
Species
This type of diversity refers to the number of species & abundance of species in a particular place
True or false: An ecosystem with high genetic diversity is healthier than an ecosystem with low genetic diversity.
True
False
The lionfish is a venomous fish found primarily in the Red Sea and the Indian Ocean. In the 1990s, lionfish were accidentally released into the Atlantic Ocean, where they found abundant resources and favorable environmental conditions. Which of the following scenarios is most likely to result in the lionfish having a major impact on the communities into which they were introduced?
With no natural predators, the lionfish population will become very large.
Some native species of invertebrates will develop a resistance to lionfish venom.
Define genetic diversity
variation of genes within a species or population in a given area
variety of ecosystems in a given area
system made up of all the living and nonliving things in a given area
disturbance in the environment conditions that cause genetic changes to occur in organisms
Define ecosystem diversity
variety of ecosystems in a given area
variation of genes within a species or population in a given area
variety of life in Earth's land, freshwater, and marine ecosystems
changes to an ecosystem that affect how the parts of it interact
Greater ____________________ means there are more habitats to support different types of organisms.
Ecosystem Diversity
Species Diversity
Genetic Diversity
Define species diversity
a variety of genes and traits within a species
a variety of ecosystems in a given area
