Answer:
False
Explanation:
The primary productivity is higher than the secondary productivity, or any other productivity for that matter. The primary productivity comes from the producers, and it basically represents the total biomass of the producers. The producers outnumber and outweigh all other organisms by far, so they produce significantly much more biomass than any other type of organisms, thus being rated on the top for productivity.
The correct options are:
- Matter is made of small particles.
- Matter's particles are in constant random motion or vibration
- There is empty space between matter's particles.
Anything which has mass and occupies shape is a matter. Matter is composed of particles. The particles of matter are very small in size and they attract each other. There is space between the particles. The particles are in continuous random motion, thus they have kinetic energy. on absorbing energy their movement increases.
Toucan and monstera plant adapted to their environment, which gave them advantages for survival and aid. the toucan beak adapted over time to access food easier than other birds, meaning it adapted to its environment. the plant however has an adaptation that allowed it to grow its leaves longer overtime to drop water on the floor. the similarity between the two is that they both adapted in some sort of aid for themselves or environment. the contrast is that the toucan beak helps only the toucan, and the leaves only help the rainforest floor :)
