Who Eats It?
This type of organisms can be found at the bottom of the energy pyramid
producers
Plants use this process to make their own food
photosynthesis
what is the smallest ecological organization?
species/organism
This type of consumers eat the producers
primary consumers
this type of organisms break down dead organisms and bring their nutrients back to the earth
decomposers
organisms that only eat plants are called
herbivores
What is one main waste product of photosynthesis?
oxygen
this shows the interactions of both biotic and abiotic factors; it shows how everything is interconnected
ecosystem
among the following, which is considered as apex predator? eagle, lion, snake, grasshoper
lion
give an example of food chain
many examples
organisms that eat both plants and meat are called
omnivores
Cellular respiration occurs in which part of the cell?
mitochondria
arrange the following from smallest to largest:
population, community, species, biome, ecosystem
species, community, population, biome, ecosystem
this shows how energy is transferred from one trophic level to another
Energy Pyramid
Give an example of human activity that can cause ecological succession
logging/converting forest into urban ecosystems
What do we call the animals that hunt for food?
predators
What are the 3 main components needed for photosynthesis to occur?
Sunlight, water, carbon dioxide
group individuals that belong to same species that lives in the same area
population
what do we call the linear network of links that shows how organisms are related to each other by the food they eat?
food chain
define what bioaccumulation means
bioaccumulation is when toxic materials accumulate from the first trophic level towards the next ones, resulting for the apex consumers to have high levels of toxic materials
this type of organisms don't have known natural predators
apex predators
What does cellular respiration need (1) and what is its waste product (1)?
waste product: carbon dioxide
What is a community?
groups of individuals/organisms that belong to different species, living in the same area
it consists of so many food chains, showing how organisms are interrelated to one another based on what they eat
define what ecological succession mean
the process of change in the species structure of an ecological community over time.
