Five Specific Interactions in an Ecosystem Predation Competition Parasitism - Mutualism - Commensalism - Writing and Discussion About Predation

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

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

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 whales skin and feed on the remains from the whale's food.

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

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."

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. Primary consumers only obtain a fraction of the total solar energyabout 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. At each level, called a trophic level, about 90% of the energy is lost.

PlantsAnimalsOther Eukaryotic Complex Cell Structure with Organelles, especially chloroplasts/chlorophyll Contain cell walls Producers on food chains/webs At the bottom of the trophic pyramids; they absorb the most energy from the sun Give off oxygen and take in carbon dioxide (Photosynthesis) Eukaryotic Complex Cell Structure with organelles Consumers on food chain/webs Typically in the middle of the trophic pyramid Can be Herbivore, Carnivore or Omnivore Give off carbon dioxide and take in oxygen (Respiration) Prokaryotic or Eukaryotic, but most are unicellular Can be Protists, Bacteria, Fungi, and/or Achaea Mostly microscopic, simple organisms Can be Producers: if plantlike Consumers: if animal-like Decomposers: (fungi) Can be anywhere in a food chain/pyramid (depends on the organism)

Land (Terrestrial) Ocean (Aquatic) Fresh Water (Aquatic) Many & diverse types of ecosystems. There are seven major types. Location usually dependent on the latitude of the area, and amount of precipitation The 7 Major Biomes 1. Tropical Rain Forrest 2. Savanna 3. Desert 4. Temperate Grasslands 5. Deciduous Forests 6. Coniferous Forests 7.Tundra Most of Earth (~75%) 40% of all photosynthesis occurs in oceans. 3 types Shallow ocean waters Deep ocean water Deep ocean surface. Photosynthetic plankton is base of food chain. Only occurs in Deep ocean surface & Shallow ocean ecosystems No photosynthesis can occur in deep ocean because light cannot penetrate deeply into water. Smallest Ecosystem ~ 1.8% of earth's surface Support many species of life including fish, amphibians, insects and plants. Base of food-web is found in freshwater Plankton (small microscopic organisms) Home to amphibians, reptiles and almost 41% of worlds fish species. Faster moving water typically supports greater biodiversity than the slow moving water of pools (fast = more dissolved oxygen)

Nitrogen Cycle Animation Homework: Review New Notes about the Cycles and Marine Ecosystems Friday, April 26, 2013 Monday, April 29, 2013 Review New Notes about the Cycles and Marine Ecosystems 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 Friday, April 26, 2013 Monday, April 29, 2013

Marine Ecosystems Estuaries - an area in which fresh water from a river mixes with salt water from the ocean. Very productive ecosystemsconstantly 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.)

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 photosynthesistypically 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)

Ecosystems and the Media Does the media always accurately portray ecosystem interactions? Watch the following video clips and determine the following: 1)What interactions have you observed within the living things in the environment? 2)Mutualism? Commensalism? Parasitism? Predator/Prey? Symbiotic? 3)Are these relationship and interactions realistic? Why or why not? Lion King Finding Nemo: Clip 1 Finding Nemo: Clip 2

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

Page 148 Aquatic Ecosystem Water Quality WARM UP What factors impact the quality of water? Homework: Explain what causes many water quality problems and what an everyday citizen can do to reduce water quality problems. Monday April 29, 2013 Tuesday, April 30, 2013 Explain What Causes Water Quality Problems How does the factor affect water quality?

Group 1 K.I.M. cards for to define the impact of the following water quality indicators using textbook / internet. Read the original article in the Florida Times-Union by Dana Treen was entitled "Fish-killing bloom could harm humans." Chart the impact of water quality indicators Re-name this newspaper article with an appropriate answer and explain why you chose the new title.

Group 2 Using the resource pages in the back of the textbook Identify and then create an organized chart of the abiotic and biotic factors that influence the quality of water in an area. Evaluate sample water quality data Choose 6 months of the most appropriate data to show on a graph. Choose the type of graph that would best represent this data. Use the graph to help answer these questions. 1. As the temperature increases, what happens to the amount of dissolved oxygen? 2. What do you know about temperature increases that might explain why this happens? 3. As the temperature decreases, what happens to the amount of dissolved oxygen? 4. What do you know about temperature decreases that might explain why this happens?

Group 3 Read the attached information "Fish-killing bloom could harm humans" by Dana Treen and the excerpt from "Citizen's Water Quality Monitoring Manual for the St Johns River" by Robert Frease. Create an organized chart of the abiotic and biotic factors that affect water quality. Think about this: Next to oxygen, water-clean water-is our most valuable resource. Imagine that you are the public relations director for the St Johns River Water Management District. As public relations director, you need to educate the public about what they can do to have good healthy water quality. Create a display to educate the general public about the each of the factors that impact water quality.
