Environmental Science:
R and K Strategies -
Rory and I reviewed the concept of the carrying capacity and how they maintain the sustainability of an ecosystem. We then moved on to explore R and K strategies for reproduction. Every organism is directed by their genetic code to reproduce their genes. Some species create thousands of gametes every year, releasing them to fend for themselves, trusting that a few will survive to maturity and reproduce. This is the R-strategy. Other organisms produce only a few gametes over their lifetime, investing time and energy into protecting these offspring until they are mature and can reproduce. These are the K-strategy populations. Rory and I conducted a Lab on R and K strategies. We blew 30 bubbles and timed how long they survived, before hitting a surface and popping Rory recorded our data on data sheets. We then blew bubbles, and this time he did whatever he could to keep them from popping (blowing them upward or fanning them away from the wall.). We recorded the amount of time the bubbles survived. We then graphed our data to show the survivorship from each strategy.
