identify the relationship between the following combinations of organisms
algae / fungi
reindeer / arctic fox
reindeer / reindeer
previous next

Explanation:

• Algae/Fungi: Lichens are formed by the mutualistic relationship between algae and fungi. Algae provide food through photosynthesis, and fungi offer protection and help in nutrient absorption. So the relationship is mutual.
• Reindeer/Arctic Fox: Arctic foxes sometimes follow reindeer. Reindeer dig through the snow to get lichens (their food), and in the process, they expose small invertebrates and other food items that arctic foxes can eat. So reindeer act as a food source (indirectly) for arctic foxes in this context.
• Reindeer/Reindeer: Reindeer compete with each other for resources like food (lichens), space etc. within their population. But among the given options, the most relevant is that they are of the same species and interact within the population - which can be seen as a self - related interaction in terms of population dynamics (though the term "mutual/self" is a bit of a misnomer. A better term would be intraspecific interaction, but among the given options, "mutual/self" is the closest as it implies within - the - same - group interaction).

Answer:

Algae/Fungi: mutual / self; Reindeer/Arctic Fox: food source; Reindeer/Reindeer: mutual / self
