Answer:
<em>This is an example of natural selection (adaptation).</em>
Explanation:
Natural selection tends to favor those organisms which are better adapted to live in an environment.
As tortoises having flat shell and long neck were better adapted to live in barren area, hence through natural selection those organisms were favored in such an ecosystem.
As tortoises that lived on the vegetative lands were more adapted to live in such an ecosystem, hence through natural ecosystem these organisms were favored and increased in numbers.
<span>Fish have adaptable behaviors and structures so that they can
survive in the wild. These adaptations however differ with regards to context
and environment. Some fishes for example are called stonefish because they can
camouflage in environments that are composed variedly with pebbles and rocks,
and this helps them to avoid predators and thrive. Nevertheless, when these
group of organisms are strayed and become exposed to a new environment they can
be exposed and be vulnerable to predators. </span>
Answer:
Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells.
<span>Answer: Biodiversity</span>
The suppression of forest fires causes a decrease in biodiversity because
some habitats require exposure to fire. Most ecosystems of savanna, chaparral
and coniferous forests have developed with fire as an essential contributor to habitat’s vigor
and regeneration.
Additionally, wildfire suppression eliminates plant species
in fire-affected environments that require fire to germinate, established, or to
reproduce. Also, animals that depend on these plants will be affected too.
