The changes in biotic factors that occur over time to reach a stable community
The addition of nutrients or other energy to a community
Flesh removers, colonists, bone eaters, finishers.
The transfer of power in an organization
The marine ecosystem providing the most habitat and with the MOST diversity is
sandy beach
rocky shore
coral reef
kelp forest
Adaptations for attachment and the ability to bend with the waves, as well as to protect against drying out, are part of organisms in this ecosystem:
coral reef
estuary
rocky shore
kelp forest
This picture shows a(n)
sandy beach
open ocean
kelp forest
estuary
Where are coral reefs found?
Polar waters
temperate, mid-latitude waters
tropical waters
only near volcanos
Which ecosystem is this? : This is the lowest, deepest layer of the ocean; contains open plains, underwater vents/volcanoes, and canyons/trenches; there is no sunlight in this ecosystem, and the species that live here have extreme adaptations that allow them to survive
Deep sea
Open ocean
Intertidal zone
Coral reefs
Which ecosystem is this? : This is the largest marine ecosystem, and covers most of Earth's surface area; it includes all marine environments that are far from shore and that are still close enough to the surface to receive sunlight
Deep sea
Open ocean
Intertidal zone
Coral reefs
Which of the following species would you expect to find in an estuary?
Oysters
Giant squid
Reef shark
Blue whale
Which of the following is TRUE of deep sea ecosystems?
Contain high levels of oxygen due to high levels of photosynthesis
The average temperature is about 60 degrees
Subjected to pressure that is up to 1000 times greater than at the ocean surface
Minerals and nutrients are widely abundant
Which of the following is TRUE of coral reef ecosystems?
Contain low species diversity
Found mostly in polar regions
Threatened by human activities such as ocean mining and blast fishing
Highly resistant to changes in water temperature and pH
Mangroves are found on the entire east and west coast of the United States of America.
TRUE
FALSE
What is the general name for mangrove seeds?
prop roots
lenticles
propagules
seedlings
Which type of mangrove is seen here?
white
black
purple
red
Which of the following is not part of the harsh environments mangroves endure
High salt
Hard ground
Low oxygen
Varying Tides
How do mangroves help protect humans from hurricanes and tsunanis?
They release salt into the air, which neutralizes these events.
The birds, animals, and fish in the mangroves get killed instead of the humans.
They absorb up to 90% of the impact of these events.
This statement is false. Mangroves help cause hurricanes and tsunamis.
Coral reefs are intricately shaped rocklike structures that are formed as a result of
volcanic activity that is common in tropical marine environments
the gradual accumulation and fusion of skeletons of bony fish
the secretion of calcium carbonate by tiny marine animals
minerals that are washed from land ecosystems and build up
The organisms visiting this whale fall would fall into which group?
bone eater
flesh remover
colonizer
finisher
