Answers
What is the most fundamental unit of ecology? - Ans:✔✔-individual
What is the number of individuals per unit area? - Ans:✔✔-Density
The paper you read entitled, "Effects of Predator Hunting Mode on Grassland Ecosystem Function" was
an example of what kind of study? - Ans:✔✔-ecosystem
When does a dynamic steady state occur? - Ans:✔✔-When gains and losses are in balance
Ecology - Ans:✔✔-scientific study of the abundance and distribution of organisms in relation to other
organisms and environmental conditions
Community - Ans:✔✔-populations of species living together in a particular area
Fitness - Ans:✔✔-survival and reproduction- greater fitness occurs when genes are likely to be passed to
the next generation and that phenotype will come to dominate

There are 3 requirements for evolution to take place via natural selection. Please explain 1 of the 3
requirements - Ans:✔✔-traits must have variation-not everyone will have the same traits and their
possible advantages or disadvantages
Different organisms play diverse roles in ecological systems. Please pick an organisms and tell me what
role it plays. - Ans:✔✔-Plants- produce oxygen for all living things (other plants and animals) to survive
What voice and tense should you use when writing a scientific paper? - Ans:✔✔-both passive and active
voices

meadow at the Yale-Myers Research Forest in north-eastern Connecticut USA." - Ans:✔✔-We conducted
the study in a 1.5 ha meadow at the Yale-Myers Research Forest in north-eastern Connecticut USA.
When you develop an experimental design for your study you need to consider many different things.
What are 2 of the many different things you may need to consider and why should they be considered? -
Ans:✔✔-the method of collecting data because certain factors may influence or skew the results
differently leading to incorrect data. Also you need to consider how to statistically analyze the data
