Animal Habitat April 11th
San Diego Bay is home to a list of Natural resources like salt marsh and tidal flats, birds nesting, and foraging sites
An invasive species is those who evolved elsewhere and whose introduction has or is likely to cause harm to the environment or human health.
An endangered species is a species who is at the risk of extinction. An endangered species in the SD Bay is the Pacific Green Sea Turtles. The San Diego bay offers a protected foraging habitat for the sea turtles and offers a prime study area for researchers

intro to SD bay
The San Diego bay is located in San Diego county. It is 19km long and 1.6 to 4.8 km wide. It is the 3rd largest of 3 natural bays
Activities on the bay are military activities and training
The shallow end of the bay is used for evaporation to extract salt from sea water.
The San diego National Wildlife refuge complex is located in Chula Vista
The purpose of the SD National Wildlife is to preserve and protect the rare birds of southern california coastal marshes.

surface water
San Francisco and Norfolk, Virginia are on the same latitude but because San Francisco has air coming in from the ocean the temperatures in summer and winter are different.
Different ways temperatures are moderated on earth are
-Liquid water at the surface
-Distance from ocean
-Water Vapor
-Higher humidities = Moderate Temperatures

energy flows through ecosystem
QUESTIONS
1. (a) Examples of primary produceres. (b) How do they get their energy?
2. (a) The second trophic level is made up of what creatures. (b) How do they get their energy?
3. Why do predators make up the third trophic level?
ANSWERS
1. (a) plants, algae, and some bacteria. (b) use solar energy to produce organic plant material through photosythesis.
2. (a) Herbivores (plant eaters). (b) get energy through photosynthesis.
3. because they eat second trophyic level animals and other small predators.
