Homeostasis is the process by which living organisms maintain a stable internal environment despite changes in external conditions.

A hypothesis is a testable prediction about the relationship between variables, while a theory is a well-substantiated explanation of an aspect of the natural world that is based on a body of evidence.

The water cycle is crucial for maintaining ecosystems, as it regulates water availability, supports plant growth, and influences climate patterns.

An ecosystem is a community of living organisms interacting with their physical environment. Example: A forest ecosystem includes trees, animals, soil, and water.

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

Sustainability refers to meeting the needs of the present without compromising the ability of future generations to meet their own needs, often focusing on resource conservation.

Renewable resources can be replenished naturally over time (e.g., solar energy), while non-renewable resources exist in finite amounts and cannot be replaced (e.g., fossil fuels).
