Explanation:

• Parasitism (+-: one benefits, one is harmed):
• A tick on a dog: Tick benefits (feeds on dog's blood), dog is harmed (irritation, disease).
• A worm in your gut: Worm benefits (gets nutrients), you are harmed (infection, nutrient loss).
• Mutualism (++: both benefit):
• A bird eating ticks off an antelope: Bird gets food, antelope gets rid of parasites.
• Sea anemone and clown fish: Anemone gets cleaned, clown fish gets protection.
• Commensalism (+0: one benefits, one is unaffected):
• Barnacles on a whale: Barnacles get transportation, whale is unaffected.
• Moss on a tree: Moss gets support, tree is unaffected.
• The gas in a car: Not a symbiotic relationship (non - biological), so it doesn't match any symbiosis type.

Answer:

• Parasitism: A tick on a dog, A worm in your gut
• Mutualism: A bird eating ticks off an antelope, Sea anemone and clown fish
• Commensalism: Barnacles on a whale, Moss on a tree
• The gas in a car: No symbiosis type
