1. Invertebrates are just about the most abundant creatures on the earth, accounting for about 95% of all animal species. They have been around for millions of years and occupy just about every kind of habitat you can think of. Mnay invertebrates are useful to man like bees which give honey.silk worms which give silk, some are used as food and some are considered as pests responsible for destroying crops. Sampling invertebrates rquires standard protocols as these creatures are quite delicate and need to be handled carefully. 2. Qualitative sampling enables researchers to have a deeper understanding of the phenomenon they are studying. They identify the presence or absence. Quantitative sampling gives us the number / amount of substance we are studying Semi quantitative sampling shows the amount of substance relative to the threshold. 4. Ontogenetic shift is the space an individul needs as it gets older. This is related to the distribution of individuals juveniles have clustered arrangement, random arrangement when they grow and regular arrangement when they are adults. 6. Quantitative assessment of diet. Assessing current intake. - 24-hour recalls estimated food records ·weighed food records. Assessing past intake - dietary history food-frequency questionnaires (FFQ).
