The slide you are MOST likely to find in Cathy’s presentation on a frog’s life cycle and habitat is:

Terrestrial Ecosystems and Aquatic Ecosystems

This is because frogs have a life cycle that involves both aquatic habitats (like ponds or lakes for their tadpole stage) and terrestrial habitats (for their adult stage). The other options relate to specific habitats or types of organisms that are less directly relevant to frogs.

Ronald is at a lagoon after a recent storm. What should he MOST expect to find when he measures the lagoon water’s salinity?

(1 point)
Responses

lower salinity because of the tidal movement

lower salinity because of the tidal movement

lower salinity because of the precipitation

lower salinity because of the precipitation

higher salinity because of the tidal movement

higher salinity because of the tidal movement

higher salinity because of the precipitation

Ronald should MOST expect to find:

lower salinity because of the precipitation.

After a storm, increased rainfall typically leads to a dilution of the saltwater in the lagoon, resulting in lower salinity levels. Tidal movement would not usually lower salinity following a storm; rather, it could contribute to mixing, but the immediate effect of rainfall would be more significant in this context.

In which temperature range do coral reefs MOST thrive?

Responses

52°F to 60°F

52°F to 60°F

60°F to 73°F

60°F to 73°F

73°F to 80°F

73°F to 80°F

80°F to 93°F

Coral reefs MOST thrive in the temperature range of:

73°F to 80°F.

Coral reefs generally prefer warmer waters, and this range provides the optimal conditions for coral growth and health.

Chris and his family are moving to the east coast of the United States. Their new home is located where a river flows into a fresh-water lake. What ecosystem is Chris MOST likely moving to?

Responses

lagoon ecosystem

lagoon ecosystem

delta ecosystem

fresh-water estuary ecosystem

fresh-water estuary ecosystem

brackish ecosystem

Chris is MOST likely moving to a:

fresh-water estuary ecosystem.

An estuary is where freshwater from a river meets and mixes with saltwater from the ocean, but since his home is where a river flows into a freshwater lake, the term "fresh-water estuary" is applicable, specifically indicating an area where the freshwater ecosystem may be influenced by the flow of the river.

Lucy is canoeing down the Colorado River. What type of fresh-water ecosystem is she moving through?

(1 point)
Responses

wetland fresh-water ecosystem

wetland fresh-water ecosystem

limnetic fresh-water ecosystem

limnetic fresh-water ecosystem

terrestrial ecosystem

terrestrial ecosystem

lotic fresh-water ecosystem

Lucy is canoeing down the Colorado River, which means she is moving through a:

lotic fresh-water ecosystem.

Lotic ecosystems are characterized by flowing water, such as rivers and streams. In contrast, lentic ecosystems refer to still bodies of water like lakes and ponds.
