Question

1. ostriches and gazelles: they feed next to each other and watch for predators, alerting each other to danger. since the visual abilities of the two species are different, they each can identify threats the other animal would not as readily see. organism 1: helped harmed not harmed/not helped organism 2: helped harmed not harmed/not helped symbiotic relationship:
2. hermit crabs and snails: hermit crabs live in shells made and abandoned by snails. organism 1: helped harmed not harmed/not helped organism 2: helped harmed not harmed/not helped symbiotic relationship:
3. cuckoo and warbler: a cuckoo may lay its eggs in a warblers nest. the cuckoos young will displace the warblers young and will be raised by the warbler. organism 1: helped harmed not harmed/not helped organism 2: helped harmed not harmed/not helped symbiotic relationship:
4. mistletoe and spruce tree: mistletoe takes water and nutrients from the spruce, harming the tree. organism 1: helped harmed not harmed/not helped organism 2: helped harmed not harmed/not helped symbiotic relationship:
5. honey guide birds and badgers: honey guide birds alert and direct badgers to bee hives. the badgers then expose the hives and feed on the honey first. then the honey guide birds eat. organism 1: helped harmed not harmed/not helped organism 2: helped harmed not harmed/not helped symbiotic relationship:

Explanation:

1. Ostriches and gazelles: Both species alert each other to danger, so both are helped. This is mutualism as both benefit from the relationship.
2. Hermit crabs and snails: Hermit - crabs use abandoned snail shells. Snails are not affected as they have already abandoned the shells. This is commensalism where one organism (hermit - crab) benefits and the other (snail) is neither helped nor harmed.
3. Cuckoo and warbler: The cuckoo is helped as its young are raised by the warbler, while the warbler is harmed as its own young are displaced. This is parasitism.
4. Mistletoe and spruce tree: Mistletoe takes water and nutrients from the spruce tree, harming it. Mistletoe is helped. This is parasitism.
5. Honey - guide birds and badgers: Both the honey - guide birds and badgers benefit. The birds guide the badgers to hives and both get to eat honey. This is mutualism.
