3. How can moss and lichen, which may grow in the beginning of primary succession, potentially make it easier for other

organisms to grow and live in the same area later on?

Mosses and lichens made the soil suitable for other organisms especially for the large plants due to addition of nutrients in the soil.

Explanation:

In the primary succession, mosses and lichens grow first. In the secondary succession, these organisms are replaced by large plants such as shrub and trees. Mosses and lichens made the soil nutritive when they die. The dead bodies of mosses and lichens decompose and releases organic materials which is a food of large plants.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
