Answer:
Due to environmental conditions.
Explanation:
With the passage of time, environmental conditions change which causes the evolution of of four legged land animals from fish like creature. This change occurs due to change in environment. In water, there is no need for legs because fish moves with the help of fins and tail but the organisms that lives on land has legs in order to move from one place to another so we can say that change in the physical structure of organism occurs due to environment.
Try mixing two or more animals together to create an animal. Research their physical features, the environment they do well in, senses, etc.
For example:
A cat-like creature with an alligator's tail and a bird's beak.
This creature would have cat-like instincts, but be able to swim underwater to to it's alligator tail (alligators are born to swim) and sing like a bird due to it's beak. Plus you could add anything else you want.
Another thing you could do is look up fantasy animals from video games and get inspired from them!
For worlds, you probably want to build a world that your animal could survive in.
No Man's Sky, a video-game, has endless biomes and worlds that you can take inspiration from for the climate and it's features.
You could also research about any known planets (doesn't have to be in our solar system) and mix two or more together, take aspects from one planet and give it to another, etc!
I hope these ideas helped you a bit :)
Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.
Explanation:
Answer:
The relative frequency of the mutation will increase as time passes.
Explanation:
This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.
In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.
