200

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

Food availability, competition for resources, predation, disease 

,

200

Define “contrast.”

Describe differences between items.

300

Which measure of diversity looks at the number of different species divided by the square root of the total number of organisms

Species richness

300

Which distribution pattern has the best reliability and validity?

Uniform

300

Write the scientific name for the fox. 

Vulpes vulpes

300

Recall the three types of distribution patterns

Clumped, random, uniform

300

Define “compare.”

Describe similarities and differences.

400

Calculate the percentage frequency of a plant that was found in 6 out of 50 samples.

12%

400

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

400

Define the biological concept of species

Organisms that can interbreed to produce fertile offspring

400

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.



400

500

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 - ((182+2+ 0) /17 x 16

= 1- (184/272)

= 1 - 0.676

= 0.32

500

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

500

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

500

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
