Nature knows best: How the natural world is inspiring new innovations • When we look at the world around us, we see what has survived the test of time. In other words, nature doesn't just show us results - it shows us the most optimal ideas available. • As a result, scientists are creating more products that are inspired by nature. The BlackBerry phone was inspired by a butterfly's wing.
Nature-inspired designs Solar Leaf Bio-inspiration, also known as biomimicry, is a discipline that studies and learns from nature's best ideas to generate breakthrough products and technologies.

How does the availability of resources affect the number of deer over time? Oh Deer Game
Populations will increaseas much as they can. • -For instance, as long as pike have enough food (i.e. yellow perch) to eat in Lake Winnipeg they will continue to grow, reproduce and add to their population. 2) But, populations will not grow forever due to limiting factors (Some form of resistance from the environment will stop the population’s growth) -For example, the lack of food for pike is a form of resistance or a limiting factor. If pike do not have enough food to eat their population will begin to decrease.
CARRYING CAPACITY = # the population sizethat the environment can support indefinitely, given the limiting factors
These changes in population can be graphed. The first two graphs begin in the same manner. -Point A represents the lag phase. There are very few organisms in the beginning so the reproduction rate is low. The population grows very slowly. -Then, as the young grow up and begin to reproduce, the population enters the acceleration phase at point B. -Soon the population begins to grow very quickly in the exponential phase at point C. -Exponential growth cannot occur for long due to environmental resistance, which is represented by points D,E, and F.
EARTH IS A CLOSED SYSTEM LIMITING FACTORS: factors that control an organisms growth or size of a population Ex: food, water, living space, disease, predators Source: http://www.globalchange.umich.edu/globalchange2/current/lectures/human_pop/human_pop.html
