A value closer to 1 means high biodiversity True/False
True
True/False: Quadrats sample moving animals
False
Which taxa od the Linnean classification has the greatest number of organisms?
Domain
Identify the three types of biodiversity
Genetic diversity, species diversity, ecosystem diversity
Classify chocolate as a breakfast or snack
Snack (apparently!)
N = total number of organisms
Stratified sampling ensures all habitats are measured. What is one sampling technique that could be used?
Transect, quadrat, capture-recapture method
List ALL the features of a mango from the dichotomous key
1️⃣ a. Fruit has a thick outer rind → Go to 2
b. Fruit does not have a thick rind → Go to 3
2️⃣ a. Fruit is divided into segments → Orange
b. Fruit is not segmented → Watermelon
3️⃣ a. Fruit has a central core with seeds → Apple
b. Fruit has a large single seed (stone) → Mango
Large single seed (pit/stone)
Does not have a thick rind
Name two biotic factors that could affect the abundance of an organism
Food availability, competition for resources, predation, disease
,
Define “contrast.”
Describe differences between items.
Which measure of diversity looks at the number of different species divided by the square root of the total number of organisms
Species richness
Which distribution pattern has the best reliability and validity?
Uniform
Write the scientific name for the fox. 
Vulpes vulpes
Recall the three types of distribution patterns
Clumped, random, uniform
Define “compare.”
Describe similarities and differences.
Calculate the percentage frequency of a plant that was found in 6 out of 50 samples.
12%
What is one way to reduce bias when sampling an area?
Increase size and number of samples, random-number generators, counting criteria, calibrating equipment and noting associated precision
Define the biological concept of species
Organisms that can interbreed to produce fertile offspring
Contrast the terms habitat and microhabitat
A habitat is the broader environment where an organism lives; a microhabitat is a smaller, specific area within it.
Define “determine.”
Use data to find an answer.
Calculate the Simpson's diversity of the classsroom which had 14 humans, 2 plants and 1 cockroach using the following:
𝑆𝐷𝐼=1−(Σ𝑛(𝑛−1)/𝑁(𝑁−1)).
= 1- (184/272)
= 1 - 0.676
= 0.32
Which technique involves dividing an area into subgroups (strata) and then taking a random sample from each subgroup to ensure all strata are represented?
Stratified Sampling
Explain why classification is important in understanding biodiversity.
Organises diversity
Reveals relationships
Enables identification
Facilitates communication
Supports conservation
Assists ecological studies
Tracks evolutionary change
Prevents misidentification
Guides new discoveries
Improves understanding of ecosystem function
Describe how two abiotic factors could affect the distribution of koala's
Answers vary
Temperature and rainfall could affect koala's distribution. Koalas are found only in areas that have specific temperatures and rainfall that meets their requirements for life
