Understanding the Needs of Living Things: Responses and Environments

This chapter explores the essential needs of living things, focusing on how they interact with their environments through responses to stimuli. When alarms go off or temperatures drop, living organisms react in specific ways. We delve into the concept of ecology, which studies organisms and their surroundings, highlighting the importance of food for energy and growth. Additionally, we discuss varying dietary needs among different animals and introduce the food chain, illustrating the interconnectedness of life forms in an ecosystem.
