Introduction to Ecology

Green plants, consumers, predators, organisms, and trees are which part of an ecosystem?

• Biotic factors

• Abiotic factors

Water, soil, air temperature, minerals, gases, and sunlight are which part of an ecosystem?

• Biotic factors

• Abiotic factors

all the organisms of the same group or species, who live in the same area, and have the capability of interbreeding.

• Community

• Population

• Ecosystem

 is a community of living organisms (plants, animals and microbes) in conjunction with the nonliving components of their environment (things like air, water and mineral soil), interacting as a system.These biotic and abiotic components are regarded as linked together through nutrient cycles and energy flows.

An organism that tends to have a low life expectancy and increased birth rate is known as a

• k-strategist.

• r-strategist.

An organism that tends to have a high life expectancy and takes care of their offspring longer is known as a

• k-strategist.

• r-strategist.

 growth occurs when the population size increases steadily, forms a J curve. 

• Exponential

• Logistic

 growth occurs when population growth is limited because of a finite amount of resources, forms an S shaped curve.

​If a population's death rate is ______ than its birth rate, the population will grow. ​
