what is distribution of organisms
where individual organisms are found within an ecosystem
what is abundance of organisms
the number of individuals of a species present in an area at any given time
what is a field investigation
The conduct of investigations to determine the extent of disease outbreaks or health problems.
what are sampling techniques with organisms
to determine their numbers in a given area
what is random sampling techniques
selecting a sample from a population in a way that each element has an equal chance of being included
what is transect sampling techniques
used to study the distribution and abundance of organisms along a line or pathway
what is a quadrat
-A quadrat is a square frame enclosing a known area. A quadrat can be used to sample plants or animals that don't move much
what is a pooter
A device that allows you to safely suck small insects through a tube into a jar
what is a net
A net is a two dimensional figure that can be cut out and folded into a three dimensional solid
what are positive human interactions with an ecosystem
-Recycling
-Establishing wildlife preserves and parks
-Creating green, open space laws
-Doing reforestation
-Creating environmental regulations
what are negative human interactions with an ecosystem
-Use of natural resources
-Building and expansion of cities and roads
-Pollution
-Deforestation
-Logging
what is conservation
Protecting resources against waste and harm
what are the benefits of maintaining local biodiversity
-Disease Resistance Genetically diverse populations have better chances of surviving a catastrophe like a pandemic
-Carbon Sequestration Carbon sequestration is the process of capturing and storing carbon dioxide from the atmosphere
-Storm, Flooding, and Coastal Erosion Regulation
-Food Security
-Overall Health and Happiness
what are the challenges of maintaining local biodiversity
-gaining agreements for and the monitoring of conservation schemes
-costs money
-uses land
what are environmental changes to the distribution of organisms
-Temperature shifts can change how organisms distribute themselves
-The distribution of many plants and animals change dependent on rainfall
-The composition of atmospheric gases affects the distribution of a species in an ecosystem
what are biological factors affecting food security
-increasing human population
-changing diets
-new pests and new pathogens
-environmental change
-sustainability
-cost of agricultural inputs
how does increasing human population affect food security
more people to eat food so more food needs to br grown to keep up with demand
how does changing diet affect food security
food resources are transported to be sold from areas which need them, especially meat and fish exposing vulnerable populations across continents to multiple forms of malnutrition
how does new pests and pathogens affect food security
reducing crop yields and leading to crop failure
how does environmental change affect food security
Global warming is influencing weather patterns, causing heat waves, heavy rainfall, and droughts, which can lead to food insecurity
how does sustainability affect food security
sustainable diets are low in environmental impact but can increase food waste
how does the cost of agricultural input affect food security
the higher the prices of food the less farmers can buy as they cannot afford the same amount
what are agricultural solutions
-hydroponics
-biological control
-gene technology
-fertilisers
-pesticides
what are hydroponics
The plants are grown in water with a perfect balance of mineral ions instead of soil
what is biological control
the intentional release of a natural enemy to attack a pest population
what is gene technology
modifying plants genes so they do different things
what are fertilisers 
Chemicals that give plants essential chemical elements
what are pesticides
Chemicals intended to kill insects and other organisms that damage crops
