A heterotroph is dependent on autotroph or other heterotroph for its energy whereas Autotrophs are dependent on Sun for their energy.

<h2>Explanation:</h2>

Based upon the nutrition mode, the living organisms are classified as autotrophs and heterotrophs. The organism which has the ability to prepare its own food are called heterotrophs, whereas the organism which is dependent on autotrophs and other animals are called as heterotrophs.

Basically plant are called as autotrophs as they prepare their own food with help of sunlight, and water due to the presence of chlorophyll by process called photosynthesis.

Animals and human beings are called as heterotrophs as they don't have ability to prepare their own food and in turn is dependent on plant and other animals.

Answer: c) and b) are correct.

The brain is encased in a protective bony or cartilaginous housing in craniates.

The anterior end of the nerve cord is elaborated to form a brain in craniates.

Explanation: The craniates include the chordata with well-defined heads. This includes mammals, reptiles and fishes. So we can discard the other answers. Because most craniates have functional jaws, and the adults do not lose their chordate characteristics.
