food chains
What is a food chain
sequence that shows how energy and nutrients are transferred from one organism to another in an ecosystem
What is a cycle
a series of events or stages that repeat regularly in the same order, typically returning to the starting point
What is a ecosystem
living organisms (plants, animals, microbes) interacting with each other and their non-living environment (sunlight, soil, water, air)
What is a food web
interconnected network of multiple food chains that shows how energy flows through an ecosystem
What is over hunting
excessive, unsustainable harvesting of wild animals, reducing populations faster than they can reproduce
What does the arrow in a food chain show?
the flow of energy and matter from one organism to another
why do we need cycles
recycling nutrients, conserving matter, and regulating energy flow within ecosystems and organisms.
why do we need ecosystem
providing critical services like oxygen production, water purification, carbon sequestration, and climate regulation.
why do we need food webs
they model the complex, interconnected feeding relationships in an ecosystem, showing how energy and nutrients flow between organisms.
why do we need over hunting
used as a tool for wildlife management to maintain ecosystem balance, control overpopulated species (like deer), and prevent starvation and disease.
why is it important for food chains
they map the transfer of energy and nutrients, maintaining ecological balance by controlling population numbers and ensuring the survival of species.
Why is it important to have cycles
recycling vital nutrients, regulating physiological processes, and sustaining ecosystems
why is it important to have a ecosystem
they provide essential, life-sustaining goods and services—such as clean air, water, food, and medicine—that are foundational to human survival, health, and economic well-being.
why is it important to have a food web
describe feeding relationship among species in a community.
why is it important for over hunting
In the absence of natural predators, species like white-tailed deer can overpopulate, damaging forests and reducing biodiversity.
