give the correct biological term for each of the following descriptions. write down only the correct term next to the question numbers (1.2.1 to 1.2.10) in your answer book.
1.2.1 square frames made from wood, aluminium or wire which can be carried around the research area to estimate population size.
1.2.2 a double walled cup that is next to the glomerulus.
1.2.3 the removal of nitrogenous waste material from the body.
1.2.4 what is the feeding interaction called where one animal catches and kills another animal for food?
1.2.5 temporary movement of organisms into or out of an area due to seasonal changes in resources.
1.2.6 the type of competition between members of different species.
1.2.7 what type of population growth is characterised by a lag phase, geometric phase, decelerating growth phase, and equilibrium phase?

Explanation:

1.2.1: Quadrat is a square - shaped frame used in ecological sampling to estimate population size.
1.2.2: Bowman's capsule is a double - walled cup surrounding the glomerulus in the kidney.
1.2.3: Excretion is the process of removing nitrogenous waste from the body.
1.2.4: Predation is when one animal catches and kills another for food.
1.2.5: Migration is the temporary movement of organisms due to seasonal resource changes.
1.2.6: Interspecific competition occurs between members of different species.
1.2.7: Sigmoid (logistic) growth has a lag phase, geometric phase, decelerating growth phase, and equilibrium phase.

Answer:

1.2.1: Quadrat
1.2.2: Bowman's capsule
1.2.3: Excretion
1.2.4: Predation
1.2.5: Migration
1.2.6: Interspecific competition
1.2.7: Sigmoid (logistic) growth
