Complete question: A phylogenetic tree shows that birds and crocodiles share many features. A hypothesis based on this tree predicts that these features are present in a common ancestor. Which of these predicted traits is supported by fossil evidence?
A) four-chambered heart
B) singing for territory
C) eggs and nests
D) singing to attract mates
Answer: (c) eggs and nests

A hypothesis based on phylogenetic tree shows that birds and crocodiles have ancestral connection. Fossil evidence shows that their common ancestor exhibit oviparity as a means of reproduction (i.e. laying of eggs and embryo develops within the egg), and also housed their eggs in the nest for protection against predators and other important reasons.
Answer: Providing shelter and spawning grounds to a wide range of ocean life, coral reefs serve an important role in the marine ecosystem. ... Another role is protection from strong ocean currents and high waves. As the name "barrier reef" implies, reefs act as a barrier protecting the shorelines.

Answer:
The correct answer is - option C.
Explanation:
The represented diagram shows the process of photosynthesis and how carbon dioxide and water are converted to carbohydrates and oxygen with help of light energy.
In this representation, the carbon dioxide comes from the atmosphere and transfer carbon to the cells of the plant or organism (biosphere) performing the photosynthesis in form of carbohydrates. Therefore it is a representation of the role of photosynthesis in transferring the carbon from atmosphere to the biosphere.
