Food Chain
Mention tree role of organism in a food chain
producer, consumer and decomposer
Draw a pyramid of number that matched with this food chain.
mango tree--> caterpillar --> birds --> cat --> flea (kutu)
because it is about number, so it will started by a small bar (mango tree only one) and then caterpillar larger and then birds smaller and then cat smaller and become larger in flea (the number of flea/ kutu in cat is so many ya)
hope you can understand.
what process called when water vapour which insible turn into water droplet which visible?
condensation
Tuliskan proses alami apa saja yang paling utama dalam menghasilkan oksigen di bumi, dan proses apa yang bertugas menyerap oksigen tersebut?
fotosintesis
respirasi dan pembakaran
upaya yang paling tepat untuk menanggulangi sampah platik
reuse
reduce
recycle
Explain the relation between prdator and prey
prey eaten by predator
predator eat prey as food
What is the difference between a primary, secondary, and tertiary consumer?
Primary consumers (herbivores) eat producers. Secondary consumers eat primary consumers, and tertiary consumers eat secondary consumers.
mention 4 stages in water cycle
evaporation; transpiration-->condensation-->precipitation-->infiltration;runoff
jelaskan bagiaman proses bernapas dan fotosintesis menjadi tahapan yang tidak terpisah dalam siklus karbondioksidan dan oksigen
fotosintesis membutuhkan co2 dari respirasi, respirasi membutuhkan oksgen dari fotosintesis
when human use nature for their life, sometimes it will give negative impact to nature, mention
deforestation
loss of habitat
loss of food source to animal
disaster
Complete this food chain.
...-->zootoplankton-->...--> seal-->polar bear
algae/ phytoplankton, sardines/ herring
grass-->mouse-->cat
if the mouse get 7000 joule of energy, how much energy grass got from the sun?
70000 joule
what is the different and similarity of evaporation and transpiration
sim=evaporation and transpiration is process when water changes into water vapour
Sebutkan tahapan dalam nitrogen cycle
Fiksasi nitrogen
nitrifikasi
amonifikasi
denitrifikasi
Explain how Rhizobium in peanut plant root can help to make the soil more fertile
the bacteria convert unusable atmospheric nitrogen gas (N₂) into ammonia (NH₃), a form of nitrogen that plants can readily absorb and use for growth.
What's organism called that is nor consumer and predator, it break down dead organism. mention the function of this organism
it is called as decomposer, it has function to return the energy back to the soil or back to the producer
plant is always be producer as long as they can produce their own food. make the equation of this process
CO2 + H2O ---> C6H12O6 + O2
Carbon dioxide plus water with sunlight will become glucose and oxygen
explain how plant take role in carbon cycle
organisme yang bisa menggunakan nitrogen secara langsung
bacteria that can do nitrogen fixation
- Rhizobium
- Azotobacter
- Cyanobacteria
mention the aim of making eco-enzyme
to process organic waste so it will not give negative impact in the environment
construct a food chain with these organism
A= beetle
B= Little bird
C= Snake
E= coconut tree
E --> A --> B --> C
How much the energy used for metabolic of snake if the grass got 800.000 joule of energy.
grass-->grasshopper-->mouse-->snake-->eagle
800= 80 to next tropic level,
800-80=720 j for snake
where CO2 produce, explain it in twi ways
from breathing process and as a waste product in burning process
Jelaskan masing-masing tahapan dalam siklus nitrogen
Fiksasi Nitrogen=gas nitrogen diubah menjadi amonia
Nitrifikasi=amonia diubah menjadi nitrit lalu diubah menjadi nitrat
Denitrifikasi= nitrat dalam tanah diubah menjadi gas nitrogen oleh bakteri untuk dilepas ke atmosfer
Explain how you make your eco-enzyme
just explain like your experiment
