Answer: Option 'C' is correct.
Explanation:
Since we have given that
Area of triangle LMN = 18 ft²
Area of triangle FGH = 24 ft²
Since Δ LMN and ΔFGH is equivalent triangles.
As we know the theorem which states that ratio of areas of equivalent triangles is equal to square of ratio of corresponding sides.
So, it becomes,

Hence, Option 'C' is correct.
Answer:
<u><em>Primary Succession</em></u>
Explanation:
The process by which communities are established, develop and change in ecosystems is called succession. There are two types of succession. The first is primary succession. Primary succession occurs in an area that has not been previously occupied by a community.
<u><em> Primary succession is ecological succession that begins in essentially lifeless areas, </em></u><u><em>such as regions in which there is no soil or where the soil is incapable </em></u><u><em>of sustaining life (because of recent lava flows, newly formed sand dunes, or rocks left from a retreating glacier).</em></u>
<u><em>secondary succession, type of ecological succession (the evolution of a biological community's ecological structure) in which plants and animals recolonize a habitat after a major disturbance—such as a devastating flood, wildfire, landslide, lava flow, or human activity (e.g., farming or road or building construction)</em></u>
