the living world

What are the characteristics of living beings that help define life?

Growth, Reproduction, Metabolism, Response to Stimuli, Homeostasis.

What is the process through which living organisms grow and develop?

Growth, which involves an increase in size or mass, occurs through cell division or differentiation.

How do living beings reproduce?

They can reproduce both sexually and asexually, passing on genetic material to the next generation.

What does metabolism encompass in living organisms?

Metabolic processes include anabolism (building up) and catabolism (breaking down) that sustain life.

What is homeostasis?

The maintenance of a stable internal environment through physiological mechanisms, essential for cellular function.

What is taxonomy in biology?

The science of naming and classifying organisms based on shared characteristics and evolutionary relationships.

What is the hierarchical classification of organisms?

Organisms are grouped into categories starting from broad (domains, kingdoms) to specific (genera, species).

What are the two main classifications of life forms?

Prokaryotes (like bacteria and archaea) and eukaryotes (like protists, fungi, animals, and plants).

Why is biological classification important?

It aids in studying biodiversity and ecological interactions, helping identify species and understand their ecological roles.

What role do interactions play in ecosystems?

Interactions between organisms and their environment form complex ecosystems with biotic and abiotic components.

How does energy flow in ecosystems?

Energy flows from producers to consumers and decomposers, illustrating the interdependence of organisms in food webs.

Why is understanding ecosystem dynamics important in biology?

It reveals complex biological processes and the interconnectedness of all living things in sustaining the planet.
