Asters #1 and #2 and #3
HIGHLIGHTS of the skit:
Dynamic equilibrium is a constant adjustment to change, maintaining an overall balance.
Organisms are constantly making adjustments to maintain a balance in their ecosystem in order to sustain life!
How the Environment Causes Change
An organism reacts to changing environmental conditions in order to maintain balance in their ecosystem and survive.
Plants respond to change in their environment when their leaves bend towards the sun when the direction of sunlight changes.
Some animals respond by collecting extra food for the winter, hibernating, and migrating.
Dynamic Equilibrium and Populations of the Forest
Competition helps to maintain dynamic equilibrium. Competition helps maintain that balance of the different populations of the forest.
Energy Obtained in Different Ways
Organisms carry out basic life functions, such as eating.
All living things in an ecosystem exist in a state of dynamic equilibrium…being organized systems of plants and animals that all need to take in energy constantly to sustain life.
The methods on how energy is obtained vary among organisms.
Autotrophs and Heterotrophs
Plants are autotrophs, which are organisms that are able to make their own food by using energy from the sun.
Heterotrophs are organisms, like animals and humans, which feed off of other forms of life.
An organism’s physical features can help carry out life functions in its environment. An example is a bear with strong paws and claws for hunting for food.
Other Life Functions Carried Out by Organisms of the Forest
Plants carry out life functions like germinating seeds, forming leaves, and growing into mature plants.
Animals eat, grow, reproduce, and eliminate waste.
One of the most important life functions is respiration, which is the act or process of inhaling and exhaling…breathing.
Organisms need to carry out life functions in order to maintain dynamic equilibrium and live.
If the life functions are not carried out, the organism will die.
