Surface Water Streams Rivers Lakes Ponds Marsh Swamp Bog Which of these are Flowing-Water ecosystems? Which of these are Standing-Water ecosystems?
First, let’s talk Ecology….. The interactions between organisms and their environment
Biotic Abiotic All the living parts of the environment Plants Animals Mushrooms Bacteria All of the nonliving parts of the environment Water Soil Air Wooden Chair Rotting log
Biotic Factors….It’s Alive!!! Producers-Produce their own energy. Consumers-Must consume something else
Type of Consumers: Primary consumers – herbivore Secondary Consumers - Carnivores which eat herbivores Tertiary Consumers – carnivores that eat other carnivores. Quaternary Consumers – eat tertiary, could possibly be a top predator.
Don’t forget the Decomposers! Decomposers break down dead plants, animals and waste. They are SUPER important!!!!
So an Ecosystem is….. a system formed by the interaction of a community of organisms with their environment. It includes ALL factors living and not living.
Have ecosystems changed over time? YES!
Rivers wind/slow down/widen over time Mountains erode/grow grasses/become inhabited
