Let’s Understand

Aside from the drought that dries up plants and kills animals and
typhoon that brings flood, strong wind, and lowered atmospheric

temperature, other natural calamities or disasters also affects the growth

and life cycle of plants, animals, and humans. In this lesson, you will learn
more about how other conditions affect living things.

VOLCANIC ERUPTION is another environmental condition that
can affect plants, animals, and humans.

Plants can be destroyed over a wide area, during an eruption by
hot volcanic ashes but once cools off and washed by rain, nutrients from

these ashes can make plants grow again.

conditions can also damage or kill fish and corals.
