What is the significance of DNA sequences in classifying organisms?

Back

DNA sequences help us compare organisms and show that the more sequences they have in common, the more closely related they are.

Define ecosystem dynamics.

Back

Ecosystem dynamics refers to the changes in ecosystem structure and function over time, influenced by biotic and abiotic factors.

Front

What is a phylogenetic tree?

Back

A phylogenetic tree is a diagram that represents evolutionary relationships among various biological species based on similarities and differences in their physical or genetic characteristics.

Front

Explain the concept of a niche in an ecosystem.

Back

A niche is the role or function of an organism or species within an ecosystem, including its habitat, resource use, and interactions with other organisms.

Front

What is the role of producers in an ecosystem?

Back

Producers, such as plants, convert sunlight into energy through photosynthesis, forming the base of the food chain.
