Limiting Factors Why can’t I put more than one gallon of milk into this container? What factor limits how much milk I can put into this container?
Limiting Factors Why don’t populations grow without stopping? Limiting factors prevent populations from getting too big! Limiting Factors: A resource that is so scarce (rare) that it limits the size of a population. –Examples: food, water, light, living space living space
What are some of the limiting factors in the desert?
What are limiting factors in the jungle?
What are limiting factors in a cave?
What about a limiting factor here?
Carrying Capacity Could this guy possible carry any more?
Carrying Capacity Carrying Capacity- The largest population that an environment can support at any given time.
Competition What are these two men competing for?
Competition Competition- When two or more individuals or populations try to use the same resource. –Examples: water, food, shelter, space, sunlight
Predator and Prey Who eats who? Prey- An organism that is killed and eaten by another organism. Predator- The organism that eats the prey.
Which animal is the predator? Which animal is the prey? I can out run this dude! Hey, slow down! I just want to talk.
Predator and Prey PPPPredator Adaptations- Characteristics that help predators capture their prey. –E–E–E–Examples: speed, sharp teeth, camouflage
What are the adaptations that these animals have that make them better at catching their prey?
Predator and Prey Prey Adaptations- Characteristics that help prevent them from being eaten.
Prey Adaptations –Camouflage: Coloration pattern that helps them blend in with their surroundings. Example: Walking Stick Example: Walking Stick
