Data collection and graphs (Brett) Flashcards
Categoric/Discrete variables
bar graphs needed
Continuous data
Line graphs needed
Lag or exponential growth phase
The period of slow increase between the start and rapid growth
Log or exponential growth phase
The period in which there is rapid growth or normal growth between the lag and stationary phase
Stationary phase
The period where the reaction growth meets its peak and stops/flatlines
Death or logarithmic decline phase
The moment in which the reaction declines until its eventual death
Yeast
a microorganism responsible for the bread and alcohol industry
Equation for yeast fermentation
Glucose –> Ethanol + carbon Dioxide
What does yeast need glucose for
to grow and reproduce, otherwise it dies
order of food chain
Producer –> Primary Consumer –> Secondary Consumer –> Tertiary Consumer
Trophic levels of the food chain
100% –> 10% –> 1% –> 0.1%
Predators
hunt, kill and eat other animals for food
Prey
Animals that are hunted, killed and then eaten
Adaptation
Something an organism has that is a special feature that helps them survive
What do plants compete for?
Food, space, water, soil, sunlight, oxygen, pollinators, nutrients/minerals, reproduction
What do animals compete for?
Food, partners, water, territory/land, nutrients/minerals, protect offspring, leadership, reproduction
Pesticides
chemical compounds that are used to kill pests such as insects, rodents, fungi and unwanted plants
Insecticides
Chemicals that are used to kill insects to prevent them from damaging or doing non-wanted behavior
Monoculture
Cultivation of a single type of crop on a farm
Invasive Species
A species that is introduced to a new environment, and completely takes over the environment
Fossil fuels
non-renewables that come from millions of years old plan and animal matter
Coal
Compressed carbon from plants
Oil
Compressed carbon from animals
How is the energy from fossil fuels released
They are burned/ need to combust
