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.

Biodiversity and Conservation
What is it?
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.
In simple words
- Biodiversity: variety of species, genes, ecosystems.
- 1. SERVICES: Wetland filters (school).
- 2. ACTIONS: Protect habitat first.
- Exam reminder: Exam 3-mark why biodiversity.
Important terms
BIODIVERSITY AND CONSERVATION: Biodiversity: variety of species, genes, ecosystems.
1. SERVICES: Wetland filters (school).
2. ACTIONS: Protect habitat first.
What you should learn
- 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.
Examples
- Pollination
- Clean water
- Not a medicine-extraction recipe
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.
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.
Recommended for Class 11

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.

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.
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.
Remember
- jobs ecosystems do
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.
Remember
- habitat first
Examples
- National park
- Seed bank named
- Do not take protected wildlife
Remember
- variety at three levels
- habitat loss first threat often
- services + genes + ethics
- slogans only
- jobs ecosystems do
- habitat first
- variety at three levels
- habitat loss first threat often
How the ideas connect
Exam 3-mark why biodiversity. Ecosystem services (pollination / water). Genetic store for crops. Ethical duty not to erase species.
Deeper understanding
Go beyond memorising Biodiversity and Conservation. Connect the definition to reasons, relationships, exceptions, and exam wording.
How the ideas connect
Exam 3-mark why biodiversity. Ecosystem services (pollination / water). Genetic store for crops. Ethical duty not to erase species.

Conservation slogans. No collection of protected species, no biopiracy.
- Mistake
Do not treat 1. SERVICES and 2. ACTIONS as the same idea; each explains a different part of the topic.
- Mistake
Writing only “variety at three levels” is incomplete. Link it with “habitat loss first threat often” and explain the biological reason or sequence.
- Mistake
Conservation slogans. No collection of protected species, no biopiracy.
