BiologyChapter 15: Ecology
Biodiversity and Conservation
Biodiversity: variety of species, genes, ecosystems.
Learning objectives
- Explain biodiversity and conservation in clear biological language.
- Distinguish 1. services from 2. actions.
- Use the key terms to answer a short Federal Board exam question.
Definition
Biodiversity: variety of species, genes, ecosystems. Hotspots named. Why keep it: ecosystem services (pollination, water, medicine named as a class, not a biopiracy guide), ethics, future options. Threats: habitat loss, overharvest, invasive species, pollution, climate. Conservation: parks, corridors, seed banks, captive breeding named — slogans, not a zoo-breeding protocol. Endangered vs extinct.
Important terms
- BIODIVERSITY AND CONSERVATION
- Biodiversity: variety of species, genes, ecosystems.
- 1. SERVICES
- Wetland filters (school).
- 2. ACTIONS
- Protect habitat first.
Overview
Why it matters, how it is lost:
Services
Wetland filters (school). Forest carbon. Bees pollinate crops. Genetic variety in crops vs disease. IUCN Red List named as a list, not a hunt list.
Examples Pollination · Clean water · Not a medicine-extraction recipe
Actions
Protect habitat first. Invasive control as a policy word. CITES named as a trade treaty word. Local: plant native, less waste. No instructions to collect rare species. Protected areas (national parks). Wildlife corridors connect habitats. Seed banks preserve genetic diversity. CITES regulates international trade in endangered species.
Examples National park · Seed bank named · Do not take protected wildlife
WHAT — BIODIVERSITY AND CONSERVATION
Biodiversity: variety of species, genes, ecosystems. Hotspots named. Why keep it: ecosystem services (pollination, water, medicine named as a class, not a biopiracy guide), ethics, future options. Threats: habitat loss, overharvest, invasive species, pollution, climate. Conservation: parks, corridors, seed banks, captive breeding named — slogans, not a zoo-breeding protocol. Endangered vs extinct.
WHY — Why this topic matters
BIODIVERSITY AND CONSERVATION is an independent FBISE learning unit because students must connect its structures and processes with their biological functions and examples.
HOW — How it works
SERVICES: Wetland filters (school). Forest carbon. Bees pollinate crops. Genetic variety in crops vs disease. IUCN Red List named as a list, not a hunt list. Examples: Pollination; Clean water; Not a medicine-extraction recipe. ACTIONS: Protect habitat first. Invasive control as a policy word. CITES named as a trade treaty word. Local: plant native, less waste. No instructions to collect rare species. Protected areas (national parks). Wildlife corridors connect habitats. Seed banks preserve genetic diversity. CITES regulates international trade in endangered species. Examples: National park; Seed bank named; Do not take protected wildlife. Exam 3-mark why biodiversity. Ecosystem services (pollination / water). Genetic store for crops. Ethical duty not to erase species.
In simple words
Conservation slogans. No collection of protected species, no biopiracy.
Key points
- variety at three levels
- habitat loss first threat often
- jobs ecosystems do
- habitat first

Core Idea
- Biodiversity: variety of species, genes, ecosystems. Hotspots named. Why keep it: ecosystem services (pollination, water, medicine named as a class, not a biopiracy guide), ethics, future options. Threats: habitat loss, overharvest, invasive species, pollution, climate. Conservation: parks, corridors, seed banks, captive breeding named — slogans, not a zoo-breeding protocol. Endangered vs extinct.
1. SERVICES
- Wetland filters (school). Forest carbon. Bees pollinate crops. Genetic variety in crops vs disease. IUCN Red List named as a list, not a hunt list.
2. ACTIONS
- Protect habitat first. Invasive control as a policy word. CITES named as a trade treaty word. Local: plant native, less waste. No instructions to collect rare species. Protected areas (national parks). Wildlife corridors connect habitats. Seed banks preserve genetic diversity. CITES regulates international trade in endangered species.
Exam Example
- Exam 3-mark why biodiversity.
- Ecosystem services (pollination / water).
- Genetic store for crops.
- Ethical duty not to erase species.
Common Misconception
- Do not treat 1. SERVICES and 2. ACTIONS as the same idea; each explains a different part of the topic.
FBISE Exam Check
- Define biodiversity and conservation, explain the two key parts, and use the correct biological terms.
- Exam reminder: Exam 3-mark why biodiversity.
60-second revision
- Biodiversity: variety of species, genes, ecosystems.
- 1. SERVICES: Wetland filters (school).
- 2. ACTIONS: Protect habitat first.
- Exam reminder: Exam 3-mark why biodiversity.
