Ecological Succession
Pioneer species of primary succession
Plants of a chapparall
hardy shrubs
4 seasons
Deciduous
Which of the following is NOT a freshwater ecosystem: Rivers, Lakes, Wetlands, Coral Reef
Coral Reef
A land area that is covered with water for part of the year is called:
Wetland
Pioneer species that may return first during secondary succession
Grasses and weeds
What two factors best determine the qualities of a biome (climate)?
Temperature and precipitation
Soil type of grasslands
Very nutrient rich
Name two ecological benefits of wetlands
provides habitat/spawning grounds for species, reduces flood risk, acts as sponge to purify water, recreation
What is the defining difference between the marine, freshwater, and estuary biomes?
Salinity (Concentration of salt)
A stable, mature community that undergoes little change in species.
What is a climax community?
Types of leaves of plants in a taiga/coniferous/boreal forest
Needle-like leaves with a waxy coating
Biome with 50% of the world's oxygen production
Tropical Rainforest
Where a river (freshwater) meets the ocean (saltwater)
Estuary
What are corals?
Living organisms (animals)
Type of succession that would occur after a fire or a flood
What is secondary succession?
A biome similar to a grassland, but with more precipitation and so a few more trees. Found in tropical (near equator) locations
Savanna
Animals who hibernate during the winter may live in one of these biomes
Tundra, Taiga, or Temperate Deciduous forest
Most biodiverse aquatic biome
Coral Reef
Types of organisms found at a river's headwaters
trout, minnows
Type of succession that would occur after a volcanic eruption
What is primary succession?
What do the roots of plants look like in the tropical rainforest
shallow and wide roots since the soil is thin and poor in nutrients
Adaptations of desert organisms
Must be able to conserve water
How are lake zones divided?
Amount of sunlight received
What happens to a river as it flows down the mountain
Warmer temperatures, widens out, lower levels of dissolved oxygen. More plants
