Ecosystem Processes Flashcards
Equations for photosynthesis
photosynthesis is carbon dioxide + water —> glucose + oxygen + water. A balanced chemical equation for the process can be written as 6CO2 + 6H2O —> C6H12O6 + 6O2. Overall, photosynthesis uses light energy to convert carbon dioxide into a carbohydrate
Chlorophyll
Found in Chloroplast
Level 1
Producer
Level 2
Primary consumer
Level
Secondary consumer
Level 4
Tertiary consumer
Animal that has no predator
Apex consumer
When a community of species depend on other species
Interdependence
Increase in concentration of a pollutant in a organism
Bioaccumulation
Increasing concentration of a pollutant in a food chain
Biomagnification
the role of chloroplasts in photosynthesis
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
Waxy cuticle
Waterproof upper layer prevent water loss
Upper epidermis
Transparent layer allowed lots of sunlight through
Chloroplast
Contains chlorophyll that trap sunlight and creates energy
Palisade cells layer
Tightly packed self with lots of chloroplasts. Photosynthesis occurs here
Spongy sells layer
Lots of spaces to allow gases diffuse
Guard cell
Who sells that can change shape to open or close a stoma
Stoma
A pore that allows gasses into and out of the leaf
Xylem
Transports water
Phloem
Transports food
Mineral irons;
Nitrogen n
Phosphorus p
Potassium k
Magnesium mg
Nitrates
Needed to make amino acids which are the building blocks of proteins
Yellow leaves and poor plant growth.
Phosphates
Needed to make ATP in respiration and DNA. Needed to make ATP in respiration and DNA
Purple leaves and poor plant growth
Potassium
Needed to make enzymes which are essential for photosynthesis and respiration.
Yellow leaves with brown spots and poor plant growth.
Magnesium
To make Chlorophyll which is required for Photosynthesis.
Yellow leaves with brown spots and poor plant growth.
Why do farmers use fertiliser in plants
To increase the plants amount of nutrients to make healthy crops
word and chemical equations for respiration.
word and chemical equations for respiration.
Aerobic= Glucose + oxygen to energy + carbon dioxide + water
C6H12O6 to 6C02+ 6H20+ 38
Anaerobic= Glucose to lactic acid + energy + 2
C6H1206 to C3H603
compare aerobic and anaerobic respiration.
Aerobic respiration occurs during normal activities when enough oxygen is available.
Anaerobic respiration Because during vigourous exercise when there is a lack of oxygen available
Ecosystem
And ecosystem is a part of a biome. It includes all living things in a given area, interacting with each other, and also With their non-living environments
Community
This is all different species that live in the same habitat at the same time.
Population
A population is made up of all organisms of one species living together in the same place (habitat) at the same time.
Habitat
a habitat is the type of natural environment in which a particular species of organism lives.
Biosphere
•The volume of the earth’s surface where
organisms can be found.
Biome
•The biosphere is made up of several types of
biome.
• These are classified due to their major
vegetation types, for example TUNDRA or
TROPICAL RAINFOREST.
Niche
DescriptionIn ecology, a niche is the match of a species to a specific environmental condition. It describes how an organism or population responds to the distribution of resources and competitors and how it in turn alters those same factors.
why bioaccumulation has a greater affect on top predators in a food chain
This is biomagnification, and it means that higher-level predators-fish, birds, and marine mammals-build up greater and more dangerous amounts of toxic materials than animals lower on the food chain.
Biology pollutant
DescriptionBiological pollution is the impact of humanity’s actions on the quality of aquatic and terrestrial environment. Specifically, biological pollution is the introduction of non-indigenous and invasive species.
The first railway was called
The first railway was the Stockton and Darlington Railway (1825)
1837 - Samuel Morse invented
the telegraph
1837 - Rowland Hill invented
the postage stamp
1839 - Kirkpatrick Macmillan invented
the bicycle
1843 - Isambard Kingdom Brunel built
the Great Britain steamship (using screw propellers).
1885 - Karl Benz invented
the motor car.
Cheap Trains Act
made railway companies offer a greater number of cheap trains for workers.
How was trade effected by the shipping industry
The growth of the shipping industry allowed a huge growth in worldwide trade.
All Red Line’.
By 1902, the whole British Empire was linked together by a network of telegraph cables called the ‘All Red Line’.
