The right answer is b. Tree.
Some plants (like trees) have evolved with different unusual nutritional adaptations over time. Heterotrophic plants are plants that use only or partly a source of organic carbon to grow, unlike the most common autotrophic plants, which use inorganic carbon and water to grow, often through the process of photosynthesis (photoautotrophic).
I think the egg because it’s the start of their life cycle, or something. I don’t think the chicken came first bc the egg would be the baby and the chicken the adult.

Option (B) Habituation is the right answer.
Crocodiles that ignore birds cleaning their teeth instead of eating them is an example of habituation.
<h3>Crocodile and avian mutualism—is it real?</h3>
- One of nature's best instances of mutualism is the interaction between a Nile crocodile and an Egyptian plover bird.
- A crocodile will simply open his mouth and wait when he needs to floss.
- The plover bird will involuntarily swoop down and grab meat scraps from the crocodile's gaping jaws.
<h3>Why do crocodiles develop a habit of approaching the birds that brush their teeth?</h3>
- It is a phenomenon of evolution that when a bird used to sit in a crocodile's mouth, the crocodile didn't eat it; instead, the crocodile used to allow the bird to sit in the mouth and clean the crocodile's teeth so that they can live longer, whereas the birds could get the free food from the crocodile's mouth.
- It is an illustration of how the two are mutually beneficial.
- The same is true now because crocodiles have adapted to the fact that birds will clean their teeth, so rather than consuming them, they ignore the birds.
