Algae refer to a photosynthetic group of organisms that possess pigments such as chlorophyll but, lack true roots, stems, and leaves, while moss refers to a small, flowerless, green plants, which lack true roots, growing in low carpets or rounded cushions in damp habitats.

Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers. 5 – 8. Biology, Ecology, Conservation.

Macroalgae are classified into three major groups: brown algae (Phaeophyceae), green algae (Chlorophyta), and red algae (Rhodophyta).

Mosses reproduce by spores, which are analogous to the flowering plant’s seed; however, moss spores are single celled and more primitive than the seed. Mosses also spread asexually by sending out new shoots in the spring from last years plants as well as fragmentation.

Asexual reproduction (called facultative parthenogenesis) is not common in snakes, but it does happen. Sharks, birds, and lizards are the only other vertebrates capable of reproducing this way [PDF]. It’s also possible the female snake has been storing sperm and waiting to fertilize her eggs with it.

A large percentage of microorganisms, the prokaryotes (those without a nucleus) reproduce asexually. Bacteria and archaea primarily reproduce using binary fission. One cell simply splits into two identical cells.

Mosses, unlike fungi, are plants. They are typically small – from 1 – 10 cm – although they can be larger. They don’t have flowers or seeds, but they do produce spores, as fungi do. Because mosses don’t have a root system, they must live in somewhat damp environments to get their water and nutrients.

Bryophyta

Spanish moss is not parasitic and therefore does not harm the trees directly. The plant obtains its own nutrients. But large growths of Spanish moss can block out the sun and hinder photosynthesis in the leaves of host tree occasionally causing minor damage.

7 interesting things about moss

• They’re ancient plants. Mosses are non-flowering plants which produce spores and have stems and leaves, but don’t have true roots.
• They don’t have roots.
• They’re tougher than they look.
• Soaking it up.
• Temperature control.
• Some mosses are luminous.
• Biodiversity.

What are pioneer species? Moss, a common pioneer species on bare rocks. Organisms specifically adapted to colonize bare, lifeless areas and begin an ecological community are defined as pioneer species.

The first organisms to appear in areas of primary succession are often mosses or lichens. These organisms are known as pioneer species because they are the first species present; pioneer species must be hardy and strong, just like human pioneers. With this plant life come animal species that feed on the plants.

Pioneer species is the first to colonize an ecosystem previously disturbed or damaged. Eventually, the pioneer species could contribute nutrients to the soil when they die and thereby provide a better habitat for secondary succession.

Primary succession begins in barren areas, such as on bare rock exposed by a retreating glacier. The first inhabitants are lichens or plants—those that can survive in such an environment. Over hundreds of years these “pioneer species” convert the rock into soil that can support simple plants such as grasses.
