Tentacles of an octopus as well limbs of a lizard are analogous structures.
Analogous structures or organs perform the same function in different organisms that bear no resemblance to each other anatomically. Analogous structures are formed as a result of convergent evolution, i.e. different structures evolving for the similar function and thus having similarity. Tentacles of an octopus as well as limbs of a lizard are used for the similar function, i.e. locomotion in this case.
On the other hand, homologous structures result from divergent evolution. Homologous organs contain a similar basic structure but perform distinct functions in different organisms.

Answer:
Heterotrophs obtain chemical energy for their survival by eating plants and animals.
Explanation:
- The chemical energy that organism need comes from food. They break this food down to obtain energy.
- Depending on their source of nutrients , they are classified into: Autotrophs and Heterotrophs.
- Autotrophs use sunlight and photosynthesize to produce their own food. They are often known as producers.
- Heterotrophs are beings that can't prepare their own food and consume other organisms to obtain energy.They are also called consumers.
