<u>Answer:</u>
<em>It is the biosphere and hydrosphere that interact when a drought causes a wildfire that destroys a forest.
</em>
<u>Explanation:</u>
Hydrosphere consists of all the water bodies of earth like oceans, seas, rivers, lakes etc. a drought occurs due to scarcity of water which affects the hydrosphere. The scarcity of water causes plants and trees to dry up and become more prone to catching fire
Biosphere includes all the living organisms of the earth. It includes plants, trees, birds, insects, animals etc. A drought dries up a whole area and a small fire that starts up somewhere in a forest would then engulf the whole forest.
Well its apart of the food chain, but is also apart of the circle of life if you call it that. If you need more detail please ask in the comments I can explain more if needed
Outside factors seem to effect the Earth on some aspects and seem not to effect it on others.
For example, water tide is effected by the moon's gravitational force, and seasons effects by Earth's location and orientation in relation to the sun.
Some of the environment seems to result by processes internal to Earth's "closed system". For example, overpopulation occurs when a species' population exceeds the carrying capacity of its ecological niche. In this case, ecology plays as the "closed system" factor. Another example can be Drought, which can result from a number of causes based of the weather and climate of a region. In this case we can say those causes are bound to the "closed systemness" of Earth, and shape the problematic situation of drought.
Hope this is helpful :)
