Two Rivers Wildlife Park presents a discussion about ecosystems, food chains and biodiversity.
Most things we have or use as human beings has its roots in nature, and most of these in wildlife. Without wildlife, the planet could not support human life!
Most importantly, all living things perform essential functions that keep this complex planet suitable for life. We can think of these as “jobs” that they have.
Humans do not produce food. Plants and other animals produce it for us. Can you think of some food that comes from wildlife?
Most wood and paper products still come from natural forest ecosystems .
Aspirin, one of our most common drugs, comes from the bark of the willow tree, though it is now manufactured synthetically.
Clothing! We get our cotton comes from the cotton plant, and leather from cows. Many synthetic fibers come from the remains of wildlife of several million years ago….oil!
Here are some words that describe the food habits of animals.
What category do you fit in?
Carnivore means a meat eater (example: cougar)
Omnivore means an animal that eats both plants and animals.
(example: black bear)
How do you find your food? At the grocery store? In the refrigerator? In the garden? Do you hunt for your own food?
There are names for different roles or “jobs” at various levels of the food web.
Green plants are called producers.
Animals that eat plants are called primary or first level consumers.
Animals that eat other animals are called secondary or second level consumers
Animals that eat secondary consumers are called tertiary consumers.
Microorganisms and fungi that make a living breaking down dead material are called decomposers.
An ecosystem is a complex concept. It is:
An ecosystem can be a small area,
like a pond.
An ecosystem can be a larger area like the Mira River and surrounding area.
An ecosystem can be contained on an
island, like Sable Island.
An ecosystem can be a forest or part of a forest.
Biodiversity is the variety of living things. Biodiversity can refer to a species or where the species lives.
Diversity can refer to how many or how few different species live in an ecosystem. OR It can also refer to the number or diversity of ecosystems across the landscape.
Example: Cape Breton Island has a large variety of forest types, rivers, ponds, streams, meadows and grasslands. It has good biodiversity!
A diverse ecosystem is a healthy ecosystem
