Ecological Succession

Front

Which type of environment experiences the least change in species over time? Options: 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.

Back

an ecosystem with a climax community

Front

Which plant characteristics are common to pioneer species?

Back

plants with roots that act as wedges to slowly break apart rocks

Front

A hurricane hits a coastal prairie and destroys the habitat. Years later there is an appearance of small plants with rapidly spreading roots on newly formed coastal sand dunes. This vegetation describes

secondary succession

Front

What is the relationship between ecological succession and equilibrium in an ecosystem?

Back

Ecological succession helps maintain equilibrium in an ecosystem.

Front

Order of stages in ecological succession (refer to diagrams).

Back

4, 2, 1, 3

Front

Differences in species diversity between primary and secondary succession?

Back

Species diversity is greater in the ecosystem undergoing secondary succession because the soil already contains seeds and spores of various species.

Front

The graph below shows the changes in the number of species in an ecosystem. Which event was most likely the cause of the changes in species diversity in this ecosystem?

Options: A large volcanic eruption, A flash flood, A small tornado, A migration of locusts

Back

A large volcanic eruption

Front

What effect does continual mowing have on the ecology of a soccer field composed of native grasses in East Texas?

Back

Mowing maintains a low species diversity by inhibiting further succession.

Front

A student studying primary succession should focus on which of these communities? Options: Open oak woodland, Mesquite grassland, Floodplain, Granite rock

Back

Granite rock

Front

What type of succession is shown going from figure A to figure B?
