 As a multicellular organism you have needs that must be met everyday.
multicellular organisms are organisms that consist of more than one cell, in
contrast to unicellular organisms. each cell is specialized, and can perform
more that one task. multicellular organisms have to eat, sleep and breath.
 They also need to respond to challenges or obstacles in their environments.
humans animals and insects are all figures of multicellular organisms. the first
form of a multicellular organism is found to be 3.8 to 4.5 billion years ago.
 3 examples of multicellular organisms are plants
humans and ants. plants are specialized because they
go through a faze called photosynthesis. Which is
where they take water from the roots to the leaves, and
absorb sunlight.
 humans are specialized because they consume food
and water every day, and they need sleep to survive.
and finally ants are specialized because they are hard
workers just to satisfy their queen and they help each
other out when help is needed.
 Plants are primary producers, they make food and energy
that can be found in our ecosystem. Without plants,
humans and animals couldn’t survive because we would
not have the food or energy that we need.
 Adaptations are something that times time to the
response of a changing enviroment. Although there are
several factors that limit theses adaptations such as,
availability of water, light, predation, and temperature.
 Plants respond to their environments in many
different ways , a few ways are Phototropism which is
an adaptation of how they respond to light, they may
display a bending movement to get stimuli. Or light
another example
 How they obtain food:
 Animals are consumers because they need to get there energy from
another organism. Food is a source of energy and materials for animals.
Animals need food and can get it in different ways. Feeding can be
relatively simple process for some animals. Some animals like coral
filter food from there environment. Others like bats are constantly
having to search and capture food. Three types of food groups,
Herbivores, food on plants and algae, Carnivores, feeds on other
animals, omnivores, feeds on both.
•Interaction with the environment:
•Animals respond to many different types of stimuli. They respond
with odors, sounds, sights, light, or change of environment. They
respond to hunger and thirst. Respond to other animals. Any
observable response to stimulus is described as a behavior. A bird
drinking water from a puddle is a behavior and a lion eating another
animal is a behavior. All behaviors fall in one of three general
categories: Individual behaviors, Interaction between animals of the
same species, and interaction between of different species. Some
behaviors are inherited. Individual behaviors: animals must find food,
water, and shelter. They also respond to different environments.
• Seasonal changes: animals can respond to seasonal changes by
changing their location. Certain food cant be food year round. For
example, Monarch butterflies have to fly south in the spring to get the
nessacary things they need. Not all animals can migrate. Some animals
hibernate. When the winter comes, it reduces the food supply.
Hibernation: is a sleeplike state that last for an extended time period.
The body system of a hibernating animals slows down so they need less
energy
 Producers- an organism that captures energy and
stores it in food as chemical energy.
 Consumers- Organisms that get their energy by
eating, or consuming, other organisms.
 Decomposers- Organisms that break down dead
plant and animal matter into simpler compounds.
 Food Chain- describes the feeding relation ship
between a producer and a single chain of consumers in
an ecosystem.
 Food web- a model of the feeding relationships
between many different and producers in an
ecosystem.
 Heterotrophs- an organism requiring organic
compounds for its principal source of food.
 Autotrophs- any organism capable of self-nourishment
by using inorganic materials as a source of nutrients
and using photosynthesis or chemosynthesis as a
source of energy, as most plants and certain bacteria
and protists.
 Tertiary Consumers-carnivore at the topmost level in a
food chain that feeds on other carnivores; an animal that
feeds only on secondary consumers.
 Secondary Consumers-a carnivore that feeds only upon
herbivores.
 Primary Consumers-an animal that feeds on plants; a
herbivore.
 Producers- creates food for the primary consumers
 Biome- one of the vast, nearly level, treeless plains of
the arctic regions of Europe, Asia, and North America.
 Tundra- one of the vast, nearly level, treeless plains of
the arctic regions of Europe, Asia, and North America.
 Taiga-the coniferous evergreen forests of subarctic
lands, covering vast areas of northern North America
and Eurasia.
 Desert-a region so arid because of little rainfall that it
supports only sparse and widely spaced vegetation or no
vegetation at all
 Grassland-an area, as a prairie, in which the natural
vegetation consists largely of perennial grassess,
characteristic of sub humid and semiarid climates.
 Temperate Forest- vegetation type with a more or less
continuous canopy of broad-leaved trees. Such forests
occur between approximately 25 and 50 latitude in both
hemispheres
 Tropical Forest- luxuriant forest, generally composed of
broad-leaved trees and found in wet tropical uplands and
lowlands around the Equator.
 Symbiotic Relationships (Commensalism, Parasitism,


Mutualism, Competition, Predation)
Commensalism - An association between two organisms in
which one benefits and the other is neither benefited nor
harmed.
Parasitism - The relation between two different kinds of
organisms in which one receives benefits from the other by
causing damage to it
Mutualism – Symbiosis that is beneficial to both organisms that
are involved
Competition – The relation between two or more animals that
are competing for the natural resources that they need in order
to survive
Predation – The predator prey relationships between two or
more animals
 Population- a group of organisms of the same species
that live in a particular area.
 Niche- a role that an organism plays in a habitat.
 Succession: the biological change of an ecosystem.
 Ex. A meadow with tall grasses and few trees changes
can eventually change into a forest with lots of trees
and few grasses and moist top soil.
 Primary succession: is the creation of a new
biological community.
 Ex. In cold climates forms of life are scarce, over time
new plant life and animals come back.
 Pioneer species: are the first sign of growth in a new
environment.
 Ex. In most glacier environments moss and lichen are
the first things to grow.
 Secondary succession: a change in an ecosystem
after a large impact in the biological balance.
Organisms- All animals depend
on plants
Population- A group of individual
organisms of the same species
living in a particular area
Ecosystem- Includes abiotic factors in an
area
Community- All organisms inhabiting a
particular area
Biome- The sum of all Earth’s ecosystems
