Description:Begin looking at the specific species interaction relationships. This is in the form of a multimedia notes/lecture period on PowerPoint.

Goals:Goals:Examine how interactions between a species and its environment define a species niche.

Explain how a species adapts to its niche.

Objectives: Day 6

I. List and Describe some of the adaptations of species use in predation symbiosis.

I. Adaptations of Predators

Predation: PredatorA. Organism who eat

other organismsB. Secondary

ConsumersC. CarnivoresD. Adaptations:

– Speed– Sharp Teeth or

Beak– Claws or Talons– Strength– Camouflage/

Stealth– Good Senses– Group Hunting

II. Adaptations of PreyA. Organism eaten by other

organisms

B. Primary & Secondary Consumers

C. Herbivores & Carnivores

D. Adaptations:– Speed– Size– Poison– Odor– Good Senses– Shelter– Mimicry (2 types):

• Physical• Chemical

Mimicry: imitating another organism as a means of defense or stealth

What is this?

Think about…I. Objective: List and Describe some the adaptations of

species use in predation symbiosis.

You will be designing a predator and prey that are competing for survival.

Consider the adaptations of predators and prey and what each will need in order to capture or evade the other.
