BIO TEST 2026

1

100

define population

The number of individuals of one species that inhabit a specific location

200

secondary succession

building ecosystem after natural disaster (presence of soil)

300

gametic prezygotic isolation

gametes are incompatible with eachother

400

define species

organisms that can interbreed to reproduce fertile offspring

500

scientists have found ways to convert co2 into fuel state the she concept

• Collaboration and communication – Developing these technologies often requires scientists, engineers, governments, and industries to work together.
• Development of scientific knowledge – Scientists are continually improving methods for converting CO₂ into fuels as new discoveries and technologies emerge.

2

100

describe primary consumers

autotrophic 

200

what is trophic levels?

starts off as producer, then primary to secondary to teritary consumers.

300

temporal

species mate at different times

400

community

group of populations living and interacting in one area

500

explain how human activity can lead to eutrophication

increased nitrogen in environment from the over use of nitrogen rich fertilizers, nitrogen collects in water ways allow producers to grow rapidly

3

100

binomial system of nomenclature (what two names are used)

genus and species 

200

types of adaptations?

behavioral, structural and physiological

300

ecological

two organisms are prevented from mating due to different habitats

400

ecosystem

a community and its abiotic environment

500

what is jothika

freak

4

100

what is a biotic factor 

predators, plants, bacteria etc

200

symbiotic relationships?

mutualism, commensalism and parasitism

300

behaioural

species have different breeding behaiviours

400

types of biodiversity

molecular (genetic), population (species), ecosystem

500

carbon cycle

photosynthesis, combustion, respiration, decomposition

5

100

primary succession 

creating a ecosystem from scratch (example forming simple soils that grass can grow)

200

levels of ecosystems

species, population, community and ecosystem

300

mechanical

species have different features that prohibit cross mating

400

what is a niche

role of organism in ecosystem/how they survive in environment with others

500

how a diverse ecosystem can arise from the environment left behind

explain primary succession 

pioneer species such as lichen and moss inhabits rocks forming simple soil that allows grass to grow. as soil develops and nutrients start to become available, intermediate species of shrubs and small trees begin to populate the area. after hundreds of year/great amount of time the community reaches a point where populations of plants and animals remain stable and balance exist between and the environment. this is known as a climax community
