Students will answer the driving question: What happens to radiation when it reaches the Earth? Some fun, creative 3D modeling challenges with CAD software (Tinkercad)!
Competition - the relationship between species that attempt to use the same limited resource (e. g. hyenas fighting with lions over a carcass or trees competing for sunlight at the top of the canopy). However, even though population growth has decreased compared to the exponential phase, it is still increasing as natality rate still exceeds mortality rate. Graphing a third factor (e. pH) at right angles to the first two creates a niche volume. Hydrofracking - with Turbidity Data.
A number of factors besides imperviousness can influence the diversity and density of macroinvertebrates present in an aquatic ecosystem. What are the factors affecting the distribution of organisms in an aquatic and terrestrial habitat. Students complete their work for GROW by working in groups to create advertisements that teach the public about nutrient cycling, and GROW's research and products. Abnormally low diversity in an ecosystem can indicate a pollution problem or other habitat change that is affecting the ecosystem.
