3. Interactions in an Ecosystem Predation Competition Whale Shark eats plankton and small fish Hawks and fox eat mice.

4. Interactions in an Ecosystem Parasitism Mutualism Mosquito sucking blood from animals. Oxpecker Bird eats ticks and parasites. Beasts get pest control

5. Interactions in an Ecosystem Mutualism Remora sharks have an adhesive disk on their dorsal surface, with the help of which they attach themselves to whales and then, clean the whale’s skin and feed on the remains from the whale's food.

6. Interactions in an Ecosystem Commensalism • "The pearlfish uses the sea cucumber for a hide-out from predators. The pearlfish will live in the sea cucumber’s anus, backing into the hole tail-first so its head can stick out."

7. Interactions in an Ecosystem Commensalism • Glass shrimp, which are almost completely see through, will attach to the chocolate chip sea star and take on its coloration. This helps the shrimp camouflage itself so it is not eaten by predators."

10. Nearly all of the energy that drives ecosystems ultimately comes from the sun. Solar energy, which is an abiotic factor, by the way, enters the ecosystem through the process of photosynthesis. At each level, called a trophic level, about 90% of the energy is lost. Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat.

Friday, April 26, 2013Monday, April 29, 2013 Friday, April 26, 2013Monday, April 29, 2013 Review New Notes about the Cycles and Marine Ecosystems Marine Ecosystems and Media Marine Ecosystems - interdependence of all organisms living in the ocean, in shallow coastal waters, and on the seashore. Abiotic Factors water pressure light dissolved gasses temperature salinity Biotic Factors – broken into zones because the biotic factors differ depending on location Marine Trophic Pyramid – See example • WARM – UP • View the nitrogen cycle animation and explain, in your own words, what is occurring. • Nitrogen Cycle Animation Homework: Review New Notes about the Cycles and Marine Ecosystems Page 145 Page 146

22. Marine Ecosystems Estuaries - an area in which fresh water from a river mixes with salt water from the ocean. • Very productive ecosystems…constantly receive fresh nutrients from the river and from the ocean • The Chesapeake Bay is the largest estuary in the United States. It produces large amounts of seafood each year, supports many species of wildlife, and provides recreation for millions of people. • Ecosystems of the bay are threatened by several environmental problems (pollution, runoff, etc.)

23. Marine Ecosystems • Coral Reefs - limestone ridges built by tiny coral animals, which slowly accumulate and form coral reefs. • Supports life of thousands of species of plants and animals; one of the most diverse ecosystems on Earth. • Corals need clear and warm salt water for photosynthesis…typically found in shallow, tropical seas. • Fragile to pollution and human activities. Pollution, change in water temperature, and runoff can devastate a reefs ecosystem (27% in the world are currently in danger)

24. Ecosystems and the Media Does the media always accurately portray ecosystem interactions? Watch the following video clips and determine the following: • What interactions have you observed within the living things in the environment? • Mutualism? Commensalism? Parasitism? Predator/Prey? Symbiotic? • Are these relationship and interactions realistic? Why or why not? Lion King Finding Nemo: Clip 1 Finding Nemo: Clip 2

25. Closing Question Why might film makers use unrealistic depictions of ecosystems when making movies?
