Final answer:

Biologists study ecosystems, biodiversity, genetics, and heredity. Astronomy and geology are scientific areas beyond the scope of biology.


Explanation:

Biologists study a wide range of topics related to living organisms. Two common areas of study within biology include ecosystems and biodiversity, focusing on how different species interact with each other and their environment, and genetics and heredity, exploring traits passed down from generation to generation. On the other hand, scientific areas like Astronomy and Geology fall outside the realm of biology as they deal with celestial bodies and the Earth's structure and processes.
