2. What is intraspecific competition?
- Competition between members of the same community
- Competition between members of the same species
- Competition between members of different species
- Competition between members of different habitats
3. Why is it difficult to prove that competition causes variations in a population?
- Correlation on a graph is not shown
- Competition happens very quickly
- Many other factors also influence population size
- The data collected is very specific so it is difficult to establish a link
4. How would you estimate a population size from mark-release-recapture?
- [no. individuals in first sample * no. in second sample]/no. marked individuals recaptured
- [no. marked individuals recaptured * no. in first sample] *100
- [no. marked individuals * no. marked individuals recaptured]/no. individuals in first sample
- [no. marked individuals recaptured * no. in second sample]/no. individuals in first sample
5. Why can cold temperatures affect mammal and bird populations?
- More energy is used trying to keep warm so their is less energy available for growth and reproduction
- Shivering causes a decrease in population sizes due to kinetic theory
- Enzymes act more slowly as they are not at their optimum temperature
- The enzymes are denatured so substrates cannot bind to their active sites
