The answer is b please can I have brainlyest
Fossil evidence suggests that the tiktaalik had lungs, which meant that it could breathe in air, instead of just water.
This trait allowed the tiktaalik to survive despite the low oxygen content of the shallow water because the tiktaalik would simply get its oxygen from the air. This selective advantage was passed on to the tiktaalik's offspring and over time, more amphibious creatures evolved with the ability to survive both on land and in water.

Organisms can be either producers or consumers in terms of energy flow through an ecosystem. Producers convert energy from the environment into carbon bonds, such as those found in the sugar glucose. ... Other producers includebacteria living around deep-sea vents.
The low rate of energy transfer between trophic levels makes decomposers generally more important than producers in terms of energy flow. Decomposers process large amounts of organic material and return nutrients to the ecosystem in inorganic form, which are then taken up again by primary producers
.
A pattern of energy flow through the organisms that live in any ecosystem can be observed. Producers, such as a tree, algae make their own food and begin this cycle. The producers are then eaten by primary consumers that cannot produce their own food, such as a giraffe. They eat the primary consumers
. Producers bring energyfrom nonliving sources into the community. Primary consumers eat th eproducers, which makes them herbivores in most communities
