Answer for you
Organisms depend on other species for resources such as nutrients. Parasites live in or on another organism, which is called the host. The parasite takes what it needs from the host but the host receives nothing in return and often suffers as a result. An example of parasitism is the relationship between fleas and dogs. Fleas live on dogs and feed on their blood. The dog receives no benefit but the fleas are provided with food and a habitat. Fleas attach themselves to hairs and can spread from one host to another by jumping huge distances.

Answer:
<em>The correct options are:</em>
<em>There are million of spores that are made by a single plant to help keep its population.</em>
<em>Spores can live for a long time without maturing into an adult plant.</em>
Explanation:
Spores can be described as a means of reproduction in plants like the gymnosperms.
There are millions of spores produced by a single plant so that the chances of their dispersal and maturing into new plants is maximum.
Spores also have the capability to stay dormant until the conditions become favorable for the growth of a plant from the spore.
Another adaptation of spores is that they are light weight so that they can easily be carried away by the wind.
