Food Chain How energy in food molecules flows from one organism to the next

Food Chain What type of decomposer could we add to this food chain to add nutrients to the soil?

Which is the predator? Which is the prey?

Reality Check Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

Symbiosis Objective: Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

Symbiosis Relationship where two organisms live in close association with each other.

3 Types: Mutualism Commensalism Parasitism

Mutualism Both species benefit. Butterfly benefits from getting nectar. How does the flower benefit from this relationship?

Mutualism

Commensalism One organism benefits and the other one in unaffected.

Commensalism One of the examples in the ocean is seen in sedentary crustaceans known as barnacles. These are very sedentary crustaceans, and so, they usually attach themselves to a substrate in the sea like rocks or preferably whales, seat turtles, etc. When whales and such creatures travel, the barnacles get access to nutrient rich waters and often, the morsels of food that are left behind by the whale, the barnacle catches it and eats it. These barnacles do the same thing when they attach themselves to the bodies of green sea turtles.

Reality Check Can I identify producers, consumers, scavengers, and decomposers in a food chain or food web?

Parasitism One species, the parasite, benefits from the other species, the host, which is harmed.
