Answer:
1.The intertidal zone is an ecosystem found on marine shorelines, where a multitude of organisms living on the shore survive changes between high and low tides.
2.Estuaries: Where the River Meets the Sea. Estuaries. Where freshwater rivers meet the salty open sea. There is a lot to love in an estuary.
3.Some plants, such as various species of oak, maple, magnolia, cedar and willow, can survive in conditions with high soil salinity or salt spray. However, mangroves are the only trees that grow directly in salt water
4.Salinity is the measure of the amount of dissolved salts in water. It is usually expressed in parts per thousand (ppt) or percentage (%). Freshwater from rivers has a salinity value of 0.5ppt or less.
5. An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, examples might include temperature, light, and water. In a marine ecosystem, abiotic factors would include salinity and ocean currents.
6.Explanation: Decomposers are small organisms that break down the remains of other dead organisms into simpler substances, which actually enrich the soil, and make it so that new plants that grow there will have enough nutrients to live. Some decomposers include fungi, worms, and insects.
7.A scavenger is an organism that mostly consumes decaying biomass, such as meat or rotting plant material. Many scavengers are a type of carnivore, which is an organism that eats meat. ... Scavengers, other carnivores, and omnivores, organisms that consume both plants and animals, are the third trophic level.
8.In a food chain, each organism occupies a different trophic level, defined by how many energy transfers separate it from the basic input of the chain. Food webs consist of many interconnected food chains and are more realistic representation of consumption relationships in ecosystems.
9.An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. ... Most autotrophs use a process called photosynthesis to make their food.
10.Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity. Every factor in an ecosystem depends on every other factor, either directly or indirectly.
