What type of symbiosis?
*Mycorrhizal fungi invade and live in or among roots cells of many plants. The plant provides nutrients to the fungi.
*The Mycorrhizal fungi help the host plant absorb inorganic nitrogen and phosphorus from the soil. Some mycorrhizal  fungi also secrete antibiotics which may help protect their host from invasion by parasitic fungi and bacteria.

• commensalism
• mutualism
• parasitism
• predation

What type of symbiosis?
*Remora use suckers to attach temporarily to large marine animals such as sharks, manta rays, whales, turtles, or large fish.
*The shark provides free transportation, protection, and dropped food and feces which the remora feeds on. The host is not injured.

What type of symbiosis?
*Fungi form lichens by living in a close relationship with an algae. The fungus provides a protective home for the algae,  and gathers mineral nutrients from rainwater and from dissolving the rock underneath.
*The algae gathers energy from the sun using photosynthesis. Both organisms share their nutrients with each other.
