What system do we use to bind periods, eras, etc., of time together?

Answers

Answer 1

Answer:

The Geological Time Scale

Explanation:

The Geological Time Scale is the framework in which the history of the Earth is inscribed. It combines a numerical scale that uses the million years as a unit (chronometric scale) and a scale that is expressed in relative time units (chronostratigraphic scale).

The chronometric scale is based on the measurement of certain physical properties of rocks, generally the relationship between the content of stable and unstable isotopes of the same element.

If an ecosystem is no longer able to sustain its biodiversity, what potential impact could that fact have on the carrying capacity and growth rate of the human population over time?

Answers

What would happen is if there was no ecosystem in biodiversity every organism would become effected in such a impactful way. It would Decrease population in animals and Humans

I really hope this helped :)

It could potentially lead to a decrease in the carrying capacity of the ecosystem, which could in turn lead to a decrease in the growth rate of the human population over time.

What is carrying capacity?

The carrying capacity of an ecosystem is the maximum number of individuals of a particular species that can be supported by the resources of that ecosystem. It is determined by the availability of food, water, and other resources, as well as by the presence of other species and environmental conditions. When the carrying capacity is reached, the population of that species will stabilize and may even begin to decline.

Carrying capacity is an important concept in ecology and population dynamics, as it determines the maximum size that a population can reach in a particular environment. It is important to note that carrying capacity is not fixed and can change over time due to a variety of factors, such as climate change, the introduction of new species, or the depletion of resources.

Which situation would affect an organism's niche in a positive way?

Answers

Answer:

hope it helps

Explanation:

Niche construction is the process by which an organism alters its own (or another species') local environment. These alterations can be a physical change to the organism's environment or encompass when an organism actively moves from one habitat to another to experience a different environment.

Abundant abiotic factors would affect an organism's niche in a positive way.

What is a niche?The functional role that an organism plays within an ecosystem is defined by its niche.The biotic variables, which include living features such as animals, plants, and fungus, as well as abiotic factors, influence the niche (also known as the "ecological niche"). Abiotic factors include non-living elements like sunshine, water availability, and weather, as well as resources like food and other nutrients.

a decrease in optimal temperature ranges
e.
an increase in activity level
C, a decrease in metabolic activity
an increase in metabolic activity

Answers

Answer:

C, a decrease in metabolic activity

Explanation:

In times of drought, there would be a reduction in the metabolic activity of an organism.

Most organisms found in very dry climates have adaptation to accommodate a period of drought. Water is essential for the metabolic processes in an organism. A deficiency of water will reduce these life activities. The organism can become inactive as a result of this.

The grey squirrel has increased their rate of emigration to the UK.

What is emigration?

Emigration is the act of relocating away from a resident country or place of residence (to permanently leave a country). Contrarily, immigration refers to the flow of individuals from one country into another (to permanently move to a country).

A migrant leaves their home nation and moves to their adopted one. Emigration and immigration thus both describe migration, but from the perspectives of various nations.

Demographers look at the push and pull factors that cause people to be drawn to one place and pushed away from another. Desires to escape unfavorable situations, such as scarcity of land or employment opportunities, or unfair treatment, are possible.

Therefore, The grey squirrel has increased their rate of emigration to the UK.
