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 whale’s 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 cucumber’s 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 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. At each level, called a trophic level, about 90% of the energy is lost.

PlantsAnimalsOther Land (Terrestrial) Ocean (Aquatic) Fresh Water (Aquatic)

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 world’s fish species. Faster moving water typically supports greater biodiversity than the slow moving water of pools (fast = more dissolved oxygen)
