Name 3 physical (nonliving) components of an ecosystem.
Ex. water, air, sunlight, soil, wind, temperature, climate...
Name all 3 living components of an ecosystem.
Plants (flora), animals (fauna), microorganisms
What is a habitat?
The place where animals/populations live.
What is a population? What is a community?
Population - group of 1 species of animals Community - Different populations (species) of animals interacting in an ecosystem.
What is an ecosystem?
The unique living and nonliving components of a specific area.
What is it called when the whole population of one animal does not exist anymore?
Exctinction
What are 3 things that can harm the biodiversity in an ecosystem.
Invasive species, global warming, human activity
What is biodiversity?
All of the different types of living organisms that live in an ecosystem.
What are invasive species? Why are they bad for the ecosystem?
species of organisms that are not native to an ecosystem. They are bad because they can destroy the balance of an ecosystem.
Why should we protect biodiversity?
Biodiversity keeps a balance in an ecosystem and keeps it healthy. We all need healthy ecosystems because we all depend on each other to get food, water, etc
What is a food chain?
The feeding relationships in an ecosystem.
What are producers? Give an example
Producers make their own food using sunlight (photosynthesis). Plants/grass.
What are consumers?
Consumers eat other living organisms.
What type of animals can consumers be?
Herbivores: primary consumers that eat plants/algae. Carnivores: secondary consumers that eat other consumers. Omnivores: secondary consumers that eat both.
Name all of the parts in a food chain.
Producers, Primary Consumers (herbivores), Secondary consumers (carnivores and omnivores -predators), Tertiary Consumers (predators and scavengers), Decomposers
What is the difference between decomposers and scavengers?
Scavengers find dead animals to eat- still eat the meat of the animal (still fresh). Decomposers feed on decomposing/rotting dead organisms and break it down.
