Question

Which piece of evidence would best support the claim that a savanna's physical factors have an effect on the adaptations seen in the organisms living there?

a) mammals living in the savanna are able to withstand extreme cold and high altitude with thick, dense fur.
b) savanna animals are excellent swimmers, whose webbed feet propel them through the water on the coastline.
c) many savanna plants have similar adaptations, such as being drought-tolerant and having thick bark to resist grass fires.
d) some plants have adapted to the distinct four seasons by lying dormant during the winter and sprouting in the spring after the snow melts.

Answer 1

The best evidence to support how a savanna's climate influences organisms' adaptations is the presence of drought-tolerant plants with thick bark, as these traits directly address the environmental challenges of the savanna's long dry season and periodic fires.

Step-by-step explanation:

Evidence Supporting Adaptations to Savanna Climate

The best piece of evidence to support the claim that a savanna's physical factors affect the adaptations in organisms living there would be: c) many savanna plants have similar adaptations, such as being drought-tolerant and having thick bark to resist grass fires.

This choice is the most accurate because it directly reflects the environmental pressures of the savanna biome. The savanna typically has a marked dry season which influences the flora and fauna to adapt in ways that allow them to conserve water and survive periodic fires. These adaptations are essential for species in this environment because the savanna experiences long dry seasons, leading to adaptations that enable organisms to withstand limited water availability and the periodic fires that help maintain the grassland ecosystem.

On the other hand, adaptations for extreme cold, high altitude, or a distinct four-season cycle are not characteristic of the savanna's climate. Similarly, while savanna animals may be capable swimmers, that is not directly linked to the dominant physical features of the savanna which are characterized by grasslands and seasonal aridity rather than large water bodies.
