Heterotrophs get their energy from other organisms. They must either feed on other heterotrophs or on autotrophs, which create their own energy.
Autotrophic means being able to make your own food. On Earth the only lifeforms that can make their own food are plants and a few species of bacteria such as cyanobacteria. Every other life form on Earth, pandas included, are heterotrophs meaning they get their food by consuming another life form, either a plant or another animal.
A change in the order of bases in an organism's DNA is called a mutation. Mutations can occur spontaneously or be induced by external factors like radiation or chemicals. Depending on where in the DNA the mutation occurs and the type of mutation, it can have varying effects on the organism, ranging from being harmless to causing genetic disorders.
No, the genetic information in an organism remains constant throughout its lifetime. However, gene expression can be regulated by varying factors, leading to different traits being exhibited at different stages of the organism's life.
Biologists can change the DNA code of a living organism through techniques such as genetic engineering or gene editing. These methods involve introducing changes to the organism's DNA sequence, either by adding new genes, editing existing genes, or deleting genes. This can result in desired traits or characteristics being expressed in the organism.
A point mutation is a mutation that can affect the gametes of an organism. This type of mutation involves a change in a single nucleotide in the DNA sequence, which can result in altered genetic information being passed on to offspring.
An auto-heterotrophic organism is an organism that can switch between being autotrophic (producing its own food through photosynthesis) and heterotrophic (obtaining food from external sources) depending on environmental conditions. This flexibility allows the organism to survive in varied or challenging conditions.
Proteobacteria are typically heterotrophic, meaning they obtain their energy by consuming organic compounds. However, some proteobacteria are also capable of being mixotrophic, meaning they can switch between autotrophic and heterotrophic modes of nutrition.
Protista, with its peculiar nature, has varieties of ways to gain nutrition. Some like algae and planktons are autotrophic, while animal-like protists such as paramecium and stentor are heterotrophic. Still others are classified as being mixotrophic, which means that they are both capable of obtaining food from others and from inorganic sources.

Eubacteria can make its own food, also known as being autotrophic.
A heterotroph is an organism that requires other organism to survive. Multicellular organisms have more than one cell. So being multicellular and heterotroph means that the organism is multicelled and depends on other organisms to survive.
Spirogyra being a fresh water chlorophycean alga prepares its own food by photosynthesis. Hence it is an autotroph.

Amoeba, paramecium, and spirogyra are all classified as protists, but they belong to different groups within this kingdom. Amoeba and paramecium are both unicellular organisms, with amoeba being characterized by its irregular shape and ability to change form, while paramecium has a more defined shape and is covered in cilia for movement. In contrast, spirogyra is a filamentous green alga, primarily photosynthetic and multicellular. Therefore, amoeba and paramecium are the most similar, as they share characteristics of being unicellular and heterotrophic, whereas spirogyra is distinct in being multicellular and autotrophic.
Euglena is a protist that has structures characteristic of both autotrophs and heterotrophs. It contains chloroplasts for photosynthesis like autotrophs, but can also absorb nutrients from its environment like heterotrophs. This allows Euglena to switch between being autotrophic and heterotrophic depending on its environmental conditions.
