1. Using the following food chain, answer the questions below.
Grass →
Rabbit → Fox
a. What type of organism is the grass?
Answer: it’s a producer
Explanation: The grass is a producer because it produces food while other animals get food themselves.
The grass is the producer of the food chain. Producers are the organisms in the food chain which produce food in a food chain.
What are the producers in a food chain?Producers are the organisms which make their own food in a food chain through photosynthesis. Producers are also known as autotrophs. They get energy to work from the chemicals or the sunlight, and with the help of water, these organisms convert the light energy into useable energy that is the chemical energy in the form of sugar or food particles. The most common example of a producer are the green plants.
Producers are any kind of green plants. Green plants make their food by taking sunlight and using this energy to make glucose (carbohydrate). The plant uses this carbohydrate, also called glucose to synthesize many products, such as wood, leaves, roots, and bark. Grasses are also an example of producers in a food chain as they produce glucose.

Gavin learns in science class that small objects such as meteoroids and debris can move through space at such high speGavin learns in science class that small objects such as meteoroids and debris can move through space at such high speeds that they can damage or puncture the sides of space vehicles. He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter. For his first trial, Gavin shoots a 3.0-gram pea at the model. Its speed is measured at 12 meters per second as it leaves the straw. The pea does not break the paper towel, but it bounces back off and lands on the ground.eds that they can damage or puncture the sides of space vehicles. He decides to design an experiment based on this information. Gavin uses an empty shoe box, a sheet of paper towel, and tape to build a model of a spacecraft. Then, he shoots a pea at the paper towel part of the model using a straw pea shooter.
Answer:
When the pea hit the paper towel, the paper towel applied an equal but opposite force on the pea.
Explanation:
A meteoroid is a piece of stony debris that float in space and move around the sun in different orbits and speeds in the Gavin experiment.
When the Meteoroids enter into Earth's surface?Meteoroids enter into Earth's surface with a high speed as shooting stars and called meteors. Meteors move through the atmosphere and landed on the surface and it is called a meteorite.

What are the two types and functions of vascular tissue?
Answer:
Vascular tissue transports water, minerals, and sugars to different parts of the plant. Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant. The xylem and phloem always lie adjacent to each other in a vascular bundle
