Here are some ways to break down your question:
1. Animals that *only* consume liquids:
* Some insects: Like aphids, which feed on plant sap.
* Certain parasites: Like tapeworms, which absorb nutrients from their host's digested food.
2. Animals that *primarily* consume liquids:
* Hummingbirds: They drink nectar from flowers.
* Some bats: They feed on nectar.
* Many aquatic animals: Fish, whales, and jellyfish primarily filter feed on small organisms in the water.
3. Animals that *can* consume liquids but also eat solids:
* Most mammals: Including humans, dogs, cats, cows, etc.
* Birds: While some birds are primarily nectarivores, most birds can consume both seeds, insects, and fruits, along with water.
* Reptiles: Some reptiles, like snakes, swallow their prey whole. Others, like lizards, eat insects and plants.
4. Animals that *need* liquid food in their diet:
* Young animals: Many young animals, like baby mammals, need their mothers' milk to survive.
* Animals with specific nutritional needs: Some animals, like certain birds, may need specific types of nectar or fruit juices.
To summarize: It's not about "acceptance" but about the specific needs and adaptations of each species. Some animals primarily consume liquids, some consume solids, and many can consume both.
