Zebra Shark (Marine Ecosystem)

Off to work...........................

architecture of the red spruce-Fraser fir community can be summarized as having three canopy layers: the uppermost is almost continuous and is made up of needle-leaf evergreens; the second is open and is made up of shorter, broadleaf trees; and the third is a continuous ground layer of herbs.

Biogeochemical cycle - or substance turnover or cycling of substances is a pathway by which a chemical substance moves through biotic (biosphere) and abiotic (lithosphere, atmosphere, and hydrosphere) compartments of Earth. Ecosystems have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles. In addition to being a part of living organisms, these chemical elements also cycle through abiotic factors of ecosystems such as water (hydrosphere), land (lithosphere), and/or the air (atmosphere).

Carbon cycle

Climax Community (is a historic term for a boreal forest community of plants, animals, and fungi which, through the process of ecological succession in the development of vegetation in an area over time, have reached a steady state. This equilibrium was thought to occur because the climax community is composed of species best adapted to average conditions in that area)

Decomposition - The carbon and nutrients in dead organic matter are broken down by a group of processes known as decomposition. This releases nutrients that can then be re-used for plant and microbial production and returns carbon dioxide to the atmosphere (or water) where it can be used for photosynthesis. In the absence of decomposition, the dead organic matter would accumulate in an ecosystem, and nutrients and atmospheric carbon dioxide would be depleted.

Players choose, pass, and arrange 11 different card types consisting of organisms ranging from bees to bears and environments like streams and meadows. Earn points by aligning animals with habitats where they most flourish)

Fungi (play an important role in energy cycling within, and between, ecosystems. Fungi are found in terrestrial, marine and freshwater environments, and are part of a diverse community of decomposers that break down dead plants and animals. Aside from fungi, this community includes bacteria, tiny invertebrates, such as nematodes, and larger invertebrates, like snails, beetles and earthworms)

Globigerina ooze in which at least 30% of the sediment consists of planktonic Foraminiferida, including chiefly Globigerina. It is the most widespread deposit to form from the settling out of material from overlying waters, covering almost 50% of the deep-sea floor.

Hydrophyte (are plants that have adapted to living in aquatic environments (saltwater or freshwater). They are also referred to as hydrophytes or macrophytes to distinguish them from algae and other microphytes. A macrophyte is a plant that grows in or near water and is either emergent, submergent, or floating. In lakes and rivers macrophytes provide cover for fish, substrate for aquatic invertebrates, produce oxygen, and act as food for some fish and wildlife)
