Today I will study the components of an ecosystem because I need to understand how living things depend on one another.

Limiting Factors, Carrying Capacity, & Matter Cycles Ecology 6.0 Limiting Factors, Carrying Capacity, & Matter Cycles

Limiting Factors Limiting Factors- resources or other factors in the environment that limit population growth. Examples: Food, Water, Habitat(shelter), Nutrients, Space.

Limiting Factors

When plenty of resources, populations can grow and grow and grow

Competition Competition- when populations have to compete for resources like food and space, the growth rate stops increasing for that population.

2 types of competition Intraspecific Competition Interspecific Competition

Intraspecific Competition Intraspecific Competition- when members of the same species compete for resources(food, mates).

Interspecific Competition Interspecific Competition- Members of different species compete for resources(food, space).

How many different predators?

Carrying Capacity Carrying Capacity- (K) is the maximum population size that can be supported in a particular area without destroying the habitat.

Carrying Capacity Dependent on limiting factors -food -space -shelter -nutrients

Example Let’s say that you can only have a family the size of how many bedrooms there are in your house. How many family members can you have?

In my apartment 4 years ago

2 bedrooms= only me and my wife. We can’t have a kid 2 bedrooms= only me and my wife. We can’t have a kid. We have to sell Beckett.

What is the limiting factor? In a habitat that has enough water, cover and space to support 20 rabbits, there is only enough food for ten rabbits. What is the limiting factor? How many rabbits can live there?

What is the limiting factor? Limiting factors are things that prevent a population from growing any larger. For example, 10 rabbits may live in a habitat that has enough water, cover and space to support 20 rabbits, but if there is only enough food for ten rabbits, the population will not grow any larger.
