Ocean Tides

Tides are very long waves. They play a very important role in the natural world. They are not just waves, though. They're long lasting, and as the sun rises in the east and the sun comes out at night, we are confident it is due to attraction of the moon and the sun.

Carrying Capacity:

The number of people, other living organisms, or crops that a region can support without environmental degradation.  

4 resources needed for survival:

                                                                  Water

                                                                   Sun

                                                                 Plants

                                                                Oxygen

How populations changed over time:

Reef damage, runoff, and human waste was increasing. most of it killed some of the underwater animals.

Limiting Factors:

an environmental factor that tends to limit population size.

Example: Predation, Competition, and herbivory.

Predator prey relationship:

A shark eating a fish.

producer:

an organism that produces its own food through photosynthesis and constitutes the first trophic level in a food chain; an autotraph.

Herbivore:

an animal that feeds on grass and other plants.

Omnivore:

an organism that eats both plants and animals.

Carnivore:

an organism that eats only animals.

Decomposer:

An organism that feeds on organic material.

Scavenger:

An organism who feeds on dead organic matter.

Food chains vs. Food webs

FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACHOTHER

FOOD WEBS show how plants and animals are interconnected by different paths.

Energy Pyramids

The Producers are always on the bottom because that's the beginning and what gives all the consumers life and energy.
