Give 5 examples each of mutualism, communalism, and parasitism.
lys-0071 [83]
<span>1. Mutualism is a type of relationship that can be seen between two individuals of two different species to obtain benefits for both of individuals.

Examples : Coral polyps and zooxanthellae
                   bee and flower
                   Lichens
                   Rhizobium and root nodules
                   Ungulates and bacteria which live in their intestines

</span><span>2. Commensalism (this is the correct word) is a type of relationship between two organisms which belonged to two different species that one individual obtains benefits while other doesn't have any harm or benefit.

Examples : Remora and sharks
                   Orchids and trees
                   Pseudoscorpions and Beetles
                   Cattle Egrets and Livestock
                   hermit crab and sea anemone

3. Parasitism is a relationship between two organisms of two different species where one individual (parasite) gets benefits by harming other individual (host).

                    Parasitic viruses (parasite) and human (host)

In which oceanic zone do clams and crabs survive by burrowing in the sand?
Keith_Richards [23]

Answer:

Mesopelagic zone

Explanation:

The Mesopelagic zone, also referred to as the Twilight zone, is the second oceanic zone from the top, lying just bellow the Epipelagic zone. It is occupying the waters at depths between 200 meters and 1,000 meters. The sunlight is only managing to reach the top few meters of this zone, while the rest is not receiving any sunlight, thus this zone is not supporting the plant species because they need sunlight for the process of photosynthesis. There are lot of animal species that live in this zone though, and they are ll very well adapted for it, often having hard shells or heavily scaled bodies, larger lungs and heart, and very well developed gills. Some of the animals that live in here are the crabs and the clams. They have developed all the needed characteristics to live in this zone. Because they are prey to lot of larger animals, both the crabs and the clams have started to use the soft sediments at the bottom as cover, digging themselves below it, and mostly managing to evade trouble and end up as food for the other species.

A, B, and C. Luster is the light and how light reflects off of it, right?
So, in that case, a non metallic mineral, (think coal) wouldn’t shine much. A metallic mineral would shine, because it’s metal. And something that’s shiny obviously shines.
Go with A B and C.
