You asked: What do you mean by environmental resistance?

: the sum of the environmental factors (such as drought, mineral deficiencies, and competition) that tend to restrict the biotic potential of an organism or kind of organism and impose a limit on numerical increase.

How does environmental resistance affect population growth?

Environmental resistance factors are all the things that keep a population of organisms from endlessly increasing. They lower the chances for reproduction, affect the health of organisms, and raise the death rate in the population.

What is an example of a resistant ecosystem?

Sand pine scrub forests have low resistance to fires due to their thin bark and the ecosystem’s dry conditions. However, they have high resilience due to the cones requiring fire to open, which then release their seeds to colonize the charred ground.

How can environmental resistance affect biotic potential?

Biotic potential increases the population of a species while environmental resistance decreases its growth. B. Biotic potential increases the population of a species while environmental resistance limits its growth. … Biotic potential and environmental resistance are both factors that increases the population of species.

What are 5 biotic factors examples?

5 Answers. Examples of biotic factors include any animals, plants, trees, grass, bacteria, moss, or molds that you might find in an ecosystem.

What are resistant species?

English ecologist Charles Elton applied the term resistance to the ecosystem properties which limit the ability of introduced species to successfully invade communities. … Higher species diversity and lower resource availability can also contribute to resistance.

What’s a resistant species?

Biological resistance is defined as a species’ innate, or natural, ability to avoid or repel attack by biotic agents (pathogens, pests, parasites, etc.)

How can an ecosystem show resistance and resilience?

Response diversity, sampling and insurance effects are said to increase the resilience and resistance of an ecosystem.

What makes an organism resistant to a chemical?

An organism may be resistant to a chemical when it contains a gene that allows it to break the chemical down into harmless substances. … The survivors happen to have a gene that protects them from the pesticide. The surviving insects pass on the gene to their offspring.

What is carrying capacity environmental science?

Carrying capacity can be defined as a species’ average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water, and mates. … Explore carrying capacity with these curated classroom resources.

Which organism has highest biotic potential?

The previous examples that we looked at also demonstrate that smaller organisms have a higher capacity for population growth—they have a higher biotic potential. Larger organisms have a lower capacity for population growth and a lower biotic potential.

What is an ecosystem answer key?

An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life. Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms.

What is abiotic in biology?

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.

Is a soil abiotic?

Soil is considered an abiotic factor since it is mostly made up of small particles of rock (sand and clay) mixed with decomposed plants and animals. Plants use their roots to get water and nutrients from the soil.
