✍️ Sample Ecology Questions & Answers
1. What does a survivorship curve Type II indicate about a population?
Type II survivorship curves are linear on a log scale, indicating a constant probability of dying at any age regardless of age class.
2. Which pattern of population dispersion is most commonly observed in nature and often results from random resource availability?
Clumped dispersion is the most common pattern, arising because resources are often patchy and social behaviors attract individuals to the same areas.
3. Which of these is a morphological adaptation?
A morphological adaptation refers to a structural or physical feature of an organism that helps it survive in its environment. A desert plant storing water in its leaves is a clear example of such an adaptation, as the succulent leaves are a physical modification for water conservation. These adaptations are visible and relate to the organism's body form.
4. How does deforestation affect the local carbon cycle?
Deforestation removes living carbon stores and often involves burning, releasing stored carbon as CO₂ while eliminating future uptake capacity.
5. Which sampling method is most appropriate for estimating the density of a sessile (non-moving) plant population?
Quadrat sampling counts individuals within randomly placed plots, making it ideal for immobile organisms like plants.
6. A life table shows that lx drops steeply in the first week of life then levels off. This pattern corresponds to which survivorship curve?
Type III survivorship curves, typical of many invertebrates and fish, show most deaths occurring very early in life with survivors having much better prospects.

What Practice Test Geeks adds beyond an AI chat for Ecology
An AI chatbot can quiz you, but it can't reproduce the exam conditions or keep your record. Here you get:
- A timed, full-length Ecology mock exam — 100 questions in 90 minutes with a 70% pass mark, modeled on the official exam's question count and time limit, followed by a score report broken down by exam domain.
- A fixed Ecology question bank: the same test every attempt, so your score is comparable from one try to the next instead of changing with every regenerated quiz.
- Progress saved on your device: completed tests, scores and missed questions stay in My Progress, so you can retake only what you got wrong.
- A printable Ecology cheat sheet you can print or save as a PDF.
- Ecology flashcards built from the same question bank.
- Free Ecology practice tests with the correct answer shown after each question.
