Question

a tapeworm attaches itself to the intestine of a cow. the tapeworm absorbs the nutrients from the cows diet, preventing them from being absorbed by the cow. the cow slowly dies.
oxpeckers eat ticks and parasites off the giraffes, and the giraffes are relieved of blood - sucking, disease - carrying parasites.
orchids grow on trees with rough bark because they support orchids better than those with smooth bark. these orchids do not harm or help the trees.
sharks and dolphins both eat fish and must compete for food.
florida scrub jays are birds that live in low growing oak scrub and scrubby flatwood trees. they must compete with each other for nesting areas.
orcas hunt in packs to take down and eat great white sharks

Explanation:

• Parasitism: One organism (tapeworm) benefits at the expense of another (cow), harming the host.
• Mutualism: Both organisms (oxpeckers and giraffes) benefit from the relationship.
• Commensalism: One organism (orchids) benefits while the other (trees) is neither helped nor harmed.
• Competition for a Biotic Factor: Sharks and dolphins compete for a living (biotic) resource (fish).
• Competition for an Abiotic Factor: Florida scrub jays compete for a non - living (abiotic) resource (nesting areas).
• Predation: One organism (orcas) hunts and eats another (Great White Sharks).

Answer:

• Tapeworm - cow: Parasitism (tapeworm benefits, cow is harmed).
• Oxpeckers - giraffes: Mutualism (both benefit).
• Orchids - trees: Commensalism (orchids benefit, trees neutral).
• Sharks - dolphins: Competition for a Biotic Factor (compete for fish).
• Florida scrub jays: Competition for an Abiotic Factor (compete for nesting areas).
• Orcas - Great White Sharks: Predation (orcas hunt and eat sharks).
