magical peaceful mysterious forests have

intrigued humans for thousands of years

and are some of the most famous

terrestrial ecosystems on the planet

their beauty economic value in the

abundance of life that they contained

has made these habitats an important

part of our culture how much do you

really know about these famous natural

areas

hey there explorers and welcome to the

forest ecosystem today we're gonna be

taking a look at some of the amazing

plants and animals that call this place

their home in exploring the interactions

that MIT all-fours two organisms

together to start our adventure we need

to look down all life in the forest

starts in the soil this is where most

plants get their food and water

many animals make their homes and

important nutrients are recycled do you

know that it takes up to a thousand

years for only one inch of soil to form

that's because swittel is actually made

up of thousands of teeny portals of

organic matter in a few minerals organic

matter is just teeny pieces of dead

plants and animals that have been broken

down over time by a process known as

decomposition this process wouldn't be

possible without the help of special

organisms known as decomposers

decomposers are special organisms such

as fungi and earthworms that consume

dead plants and animals and help turn

them into soil usually the process of

decomposition is started by scavengers

such as vultures and then continued by

these decomposers without them it would

be much harder for nutrients to make

their way back into living plants such

as the trees that dominate the forest

ecosystem

it's that large amount of organic matter

that gives for soil its dark color high

nutrient content and makes trees be able

to grow so tall right now we are in

deciduous forests made up of tall trees

that usually lose their leaves in the

winter while there are many other forest

types this is the most common forest

found here in North Carolina

in throughout the u.s. trees are the

most abundant type of producer in this

ecosystem producers are organisms that

turn sunlight water and carbon dioxide

into products like fruits leaves in bark

that provide energy for consumers that

can't make energy on their own this

means that producers are the base on

which almost all ecosystems are built

especially here in the forest not only

do trees provide food they also create

numerous homes for all kinds of

different forest dwelling animals birds

take shelter in the thick branches

snakes hunt rodents on the forest floor

deer rely on the thick vegetation to

hide from predators when trees drop

their leaves branches or die and fall

over they create habitats and food for

an entire community of invertebrates

that rely on decomposing trees for their

food and shelter those arthropods that

feed directly on the trees are an

example of primary consumers because

they are the very first animals that

take the energy created by the producers

and use it for their own growth in a

forest ecosystem primary consumers

include many insects small birds and

mammals as the second step up from

producers these organisms are important

prey sources for almost all higher-level

consumers in the forest insects in

particular are consumed by a huge

variety of birds reptiles and Finian's

and small mammals since so many

different animals like to eat insects

it's a good thing that there's plenty of

them around hoping over a single down

like this one can reveal a community of

hundreds if not thousands of the little

guys and gals going about their daily

business without these little protein

snacks they are be much less food for

secondary consumers secondary consumers

are organisms that usually rely

partially on eating other consumers and

apart on eating producers to gain the

energy that they need to live snakes are

an example of carnivorous secondary

consumers that only eat other animals

and raccoons are a good example of

omnivorous secondary consumers that may

eat other animals or plant parts there

are many many different species of

secondary consumers because of how much

energy is available to these animals

from both primary consumers and the

producers making up the middle layer of

the ecosystem secondary consumers help

keep populations of their prey items in

check while also providing energy for

the top dogs in the forest ecosystem the

apex predators not all forest ecosystems

have apex predators but even small

forest fragments usually contain enough

prey for at least one or two of these

toc level consumers also known as

tertiary consumers organisms at this

level of the ecosystem almost only

consume other consumers and require lots

of energy to remain healthy and

reproduce they have almost no natural

predators and are often among the rarest

species in natural systems one example

of a top predator is this gorgeous red

shouldered Hawk training on mammals

reptiles and even smaller birds red

shouldered Hawks keep a huge variety of

prey atoms in check ensuring that none

of their populations become too large

and take too much energy from other

organisms while nothing else in the

forest relies on the hawk as a food

source it will still provide energy for

other organisms when it dies and

decomposes to become highly nutritious

soil to fuel plant growth without a top

predators like red-shouldered Hawks

populations of lower

consumers could grow out of control and

overrun the rest of the ecosystem

healthy forests provide a number of

benefits to human beings timber harvest

provides over two hundred billion

dollars of revenue to the US alone

forested landscapes are beautiful places

to relax and enjoy nature and trees take

in and filter out toxins from the air we

breathe in the water we drink without

forests our planet will be much hotter

much drier and have much less

biodiversity thanks so much for joining

me in today's adventure and learning a

little bit more about forest ecosystems

and the organisms that make them up on

our next adventure we'll be checking out

the second type of terrestrial ecosystem

the grassland until then stay curious
