Imagine that someone from another planet is visiting Earth. They see aeroplanes and birds
moving through the sky,
Explain to the visitor why birds are alive and aeroplanes are not alive, even though they seem to
share some of the characteristics of living things

Answers

Answer 1

Birds, like airplanes, must be lightweight as well as powerful. They can fly only because evolution slimmed down their entire anatomy from their reptilian ancestors. Over time, the bones of birds have become lighter and, in the case of many "finger bones," some have disappeared altogether.

What is succession?

It is the gradual change to the community of plants and animals in an ecosystem until a stable community is reached.

Succession can be primary or secondary. Primary succession happens on newly colonized bare grounds of stones while secondary succession happens in an existing community after a period of disturbance such as wildfire.

A forest ravaged by fire will have all the animals dead or away for safety reasons. These animals may not come back until regrowth has reached a certain level.

However, propagules of grasses are often fire-resistant and even get stimulated by fire in most cases. Thus, the first type of organism to be found living in the burned area could be grasses.

Summarize the weather and ecological conditions associated with each season?

Answers

Answer: Seasons have an enormous influence on vegetation and plant growth. Winter typically has cold weather, little daylight, and limited plant growth. In spring, plants sprout, tree leaves unfurl, and flowers blossom. Summer is the warmest time of the year and has the most daylight, so plants grow quickly. In autumn, temperatures drop, and many trees lose their leaves.
