Carrying Capacity

Carrying Capacity- number of people or things that can be conveyed or held by a vehicle or container. Water, Space, Food, Shelter, Air.

The population will increase if it has Water, Space, Food, Shelter, and Air.

But if the population doesn't have these resources, they will die.

ABIOTIC- Water, Light, Soil

BIOTIC- Turtle, Tadpoles, Newt, Leech, Backswimmer.


Limiting Factors-Physiology. the slowest, therefore rate-limiting, step in a process or reaction involving several steps, Biology. an environmental factor that tends to limit population size.


Earthworms -> Snapping Turtle; The more worms the snapping turtle eats, the chances of the earthworm population will highly decrease.

Energy Roles

1. Producers= Sun, Shrub. Herbivores= Duck, Tadpoles, Backswimmer. Carnivores= 3 Spined Stickleback, Leech. Omnivores= Snapping turtle, Newt, Water Scorpion. Scavenger= Vulture. Decomposers= Fungus, Mushrooms.

Food Webs VS. Food Chains

1. food Webs are more important than Food Chains because they show more energy trails than Food chains.

2. Shrub->Mussel, and ducks-> leech-> Snapping Turtle, Newt.

3. If I removed one of the populations, the other organisms wouldn't have food and soon die out.

Trophic Levels and Pyramids


2. The energy pyramid is better than a cube or square because the greater the organism is, the smaller the energy slot is on the pyramid unlike a square or cube that would even it all out.

3. Producers are the largest base because it has more energy than the top predators that have less energy.
