Giant lycophyte trees of earth’s early forests (see figure 26.27) had microphylls, whereas ferns and seed plants have megaphylls. write a short essay (100–150 words) describing how a forest of lycophyte trees may have differed from a forest of large ferns or seed plants. in your answer, consider how the type of forest in which they grew may have affected interactions among small plants growing beneath the tall ones.

It is a process by which greenhouse gases allow the sun’s light to penetrate the atmosphere but stop the heat from escaping.

Explanation:

Greenhouse effect is the natural heating of the Earth's surface due to the fact that the sunligth waves may penetrate the atmosphere and reach the solid surface, but when the sunlight waves return after reaching the solid surface, process that changes the wavelength of the sunlight, they cannot penetrate the greenhouse gases and so the heat is kept inside the atmosphere with the consequent increase of temperature.
