All snakes are carnivores. Their diet depends on the species. Some eat warm-blooded prey (e.g., rodents, rabbits, birds), while others eat insects, amphibians (frogs or toads), eggs, other reptiles, fish, earthworms, or slugs.

An autotroph is an organism that can produce its own food. Plants fall into the first group, as they produce their own food through photosynthesis. Mammals, birds, and reptiles are examples of the second group, which rely on others for food.

Autotrophs are any organisms that are capable of producing their own food. For most, this is achieved by using light energy, water and carbon dioxide….Some examples include:

• Algae.
• Cyanobacteria.
• Maize plant.
• Grass.
• Wheat.
• Seaweed.
• Phytoplankton.

The spotted salamander and Elysia chlorotica completely does not meet the autotrophs definition. Explanation: It is because both are dependent on the algae which is present inside their bodies. Though they have green colored pigments called as chlorophyll yet they don’t possess the ability to prepare their own food.

Carnivores. Carnivores are heterotrophs that consume animals; examples of heterotrophs include lions, polar bears, hawks, salmon, and spiders.

A lot of creatures are, including giraffes, dogs, fish, horses, and lizards, but plants are not — a plant is an autotroph, because it can feed itself through photosynthesis. There are three types of heterotrophs: are herbivores, carnivores and omnivores.

In other words, most algae are autotrophs or more specifically, photoautotrophs (reflecting their use of light energy to generate nutrients). However, there exist certain algal species that need to obtain their nutrition solely from outside sources; that is, they are heterotrophic.

Frogs are not asexual. Depending on the species, frogs can reproduce through internal fertilization or external fertilization. Though frogs are not naturally asexual in the wild, scientists have long been reproducing frogs through parthenogenesis, a form of asexual reproduction, in laboratory settings.

Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter. Frog skin has a rich microbiome which is important to their health. Frogs are extremely efficient at converting what they eat into body mass.

Many people believe dogs are carnivores. In fact, dogs are omnivores, and even wolves in the wild derive nutrition from both plant and animal sources.

The short answer is that yes, technically speaking, dogs can survive and even do well on a vegan or vegetarian regimen, says Cummings Veterinary Medical Center at Tufts University. Canine digestive systems are quite capable of digesting and deriving nutrients from fruits and vegetables.
