Which of these is NOT an example of a terrestrial ecosystem?

Question

volcano site
human skin
garden plot
rotting log

Answer 1

Despite the arguments above, I say that human skin is the answer.

Terrestrial comes from the root word "Terra," which means Earth. It doesn't mean soil.

A volcano IS part of the earth; indeed, it is the connection between the earth's core and the crust (surface). A garden plot is obviously part of the earth. The rotting log could be overgrown with plants, so it would be part of Earth. Additionally, the log is consumed by organisms of the earth (decomposers like mushrooms and some bacteria).

Human skin is not a terrestrial ecosystem because no parts of the earth are involved in it. The microflora on the skin thrive entirely on the skin and its secretions - they don't need anything from the earth to survive. Further, they react to changes in their environment (for example, sweating or being rained on) independently of what's happening in the soil on earth.

Answer 2

A difficult question, because at first sight, the volcanic area, being freshly created is not thought of as a terrestrial ecosystem. But volcanic areas are colonised very quickly (such as soon after the great eruption of Krakatoa). On the other hand, the human skin is a thriving ecosystem, but is technically not terrestrial.
On balance, I think that the human skin, although an abundant ecosystem is not terrestrial, but the volcanic site, although being a sparse ecosystem, is.
Therefore.'m plumbing for the human skin as being NOT a terrestrial ecosystem.
I think it is a rather poor ambiguous question, unless there are specific text references to this point.

Answer 3

volcano site

the other three has the following characteristics of a terrestrial ecosystem:

1. the ecosystems include communities made up of a variety of species
Only organisms i.e some bacteria can thrive on a very hot lava in a volcano site

2. there are populations at the different trophic levels


3.mutual interdependence exists

4. equilibrium is reached
a volcano site is a harsh environment for life to achieve a series of generation

Answer 4

terrestrial refers to the ground, but some people loosely just mean Earth

ecosystem means living things intertwined dependency

I would say that skin and log are technically not the ground

volcano will have living organisms tho not an abundance and mostly microorganisms

garden will b loaded with life tho a human presumably planted it, then also attracts other organisms--pests

Answer 5

The human skin would be a host for parasites and not considered a terrestial ecosystem. All other answers are elements of the Earth or land matter.

Answer 6

Human skin. garden plot and rotting log would have a diversity of species within the ecosytem.

Answer 7

If it is very,very new the volcanic site will not be an ecosystem until it cools and gets rained on.

Answer 8

garden plot
